One thing that interested me in this chapter and influenced me to find out more about it was the invention of the guillotine. During the 1700’s, executions were public events where entire towns would gather to watch. Before the invention of the guillotine, execution methods were much more gruesome. These execution methods made French physician Joseph Guillotin argue for a painless and private execution method used for all classes. Although Dr. Guillotin’s ultimate goal was to eliminate the death penalty altogether, he did manage to persuade executioners to use this more humane device. The French even named the device after Dr. Guillotin, however the extra “e” found at the end of the word was added by an English poet who found the word guillotine easier to rhyme with.
Although this method was much more humane than previous execution methods there was still some controversy. It was thought that maybe some level of awareness and perhaps some perception of pain remained even after the beheading. This was thought because some individuals still blinked and twitched even after being beheaded. However, tests done by Theodor Bischoff during the early nineteenth century showed that the twitches that occurred after death were involuntary actions, therefore unrelated to consciousness.
Contrary to popular belief, Joseph Guillotin did not create the guillotine; the device was just named after him due to his effort to push more humane execution methods. The first guillotine was created by Tobias Schmidt, a German engineer. He tested it on animals and human corpses. It consisted of two fourteen-foot uprights joined by a crossbar, whose internal edges were grooved and greased; the weighted blade was either straight, or curved like an axe. The system was operated via a rope and pulley, and mounted on a high platform. The first human to be executed using this device was Nicholas-Jacques Pelletier on April 25th, 1792. The device soon gained popularity and quickly spread throughout France with minor improvements being made as time passed. However, the history of guillotine didn’t end after the French Revolution; it was adopted by other countries as well. The last person executed by the device was Hamida Djandoubi on September 10th, 1977 in France.
All in all, the guillotine is one of the most recognized forms of execution within our history. Although though it provided controversies it proved to be effective. It may seem like a ruthless device, but in actuality it was created with the best intentions.

One thing from this chapter that greatly interested me was the question of whether the guillotine was humane or not in killing someone. This question was only posed because of supposed twitches and movements that were seen from the victims after their heads were cut off. I also wanted to look into what exactly humane meant as far as killing someone. From my personal perspective they are going to be dead soon anyway and I can understand not putting them through a lot of torture but what is the difference between humane and inhumane when it comes to killing?
I learned quickly that the reason that the guillotine came into popularity in the first place was largely because it was such an egalitarian and efficient instrument. Before the guillotine criminals were executed based on their class. It could be as easy as a swing of the axe or you could be punished with the worst, the wheel where you would be spun around constantly beaten by an executioner or crowd until you were dead.
What was found was that in many cases there would be a biting motion or twitches of the face and head after the head was severed. This not only made many people very freaked out, it also raised the question of if they were really dead after their head had been severed. Today scientists have found from observation that the brain can survive for about 13 seconds after it has been decapitated due to the fact that the brain doesn't die when it's detached from the body, it dies due to a lack of oxygen. So the question was asked, if the brain can stay alive that long can the person be concious for those last thirteen seconds of their life, aware as to what has happened to them? The popular answer is no. What seems to have normally happened was that the victim would be struck unconcious by the massive blow of having their head chopped off and would therefore be unconcious when they went brain dead. It has been hypothesized that is it possible to stay conscious after having your head chopped off and from there there is no current evidence telling how long a human head could survive. Certainly no longer than their brain (13 seconds).
The final thing that I found interesting on this topic was that though many people associate the guillotine with the French Revolution (where it was first used widely) there were more beheading due to guillotine during Hitler's reign then there were during the French revolution. And although the French believed it to be a more humane way of execution, Hitler used it specifically to execute his enemies and humiliate them in the process. Given that Hitler had many other means of killing someone this would make sense to use a "barbaric" killing device to demean someone as though they are not worthy of modern killing devices.

-general history of the guillotine and it's inventor
While reading the chapter, I became very interested in the material about the guillotine used during the French Revolution. Dr. Joseph Ignace Guillotin wanted to create a painless method of executions, because France had some pretty gruesome methods of execution. Some of them included: hanging, burning, beheading with an axe or sword, or even tying the person to four different horses and making them run in different directions. Once the French Revolution began in 1789, Guillotin sent in many articles to the new French leaders in hopes of having his ideas accepted. Finally in 1792, his idea of a beheading machine was accepted. However, he did invent it. The first guillotine was invented by Antoine Louis. The machine was named the guillotine, because he put in a lot of work in making sure something like this was created.
After it was first used, there were many small improvements that had to be made. Once those improvements were made, the French assembly distributed machines to the other territorial regions. The machine was open to all people. Age, gender, and wealth were not taken into consideration. Before this was created, only the rich and powerful were beheaded.
The crimes that caused one to be sent to the guillotine were surprising, because most of them seemed like minor crimes. Most of the people sent to the guillotine were due to being counterrevolutionary. Many people during this time thought dying for liberty was heroic. Other crimes that caused people to be sent to the guillotine include: conspiracy against the republic, statements favoring the return of the monarchy, and expressions of grief at the execution of a loved one. In one extreme situation, an eighty-year old woman was sent to the guillotine for giving food and water to an Austrian. From the invention of the guillotine to the end of the French Revolution in 1799, over 15,000 people were killed by the guillotine.
During the French Revolution, a period called The Terror took place. In 1793, the French created The Committee of Public Safety. This was created to protect the Republic. However, it quickly became a dictatorship. The committee arrested and executed “anyone who either by their conduct, their contacts, their words of their writings, showed themselves to be supporters of tyranny, of federalism, or to be enemies of liberty.” All of that could have included almost everyone, so in 1793 and 1794, thousands of people were sent to the guillotine. They killed many more than the people they sent to the guillotine. They also killed by shooting them, drowning them, or even lining them up and shooting them with cannons.
Many people think The Terror was caused by the guillotine. It was such an easy way to kill people, and technically there was no human involvement. The machine was the thing killing the thousands of individuals. All of this also brought of up the argument of whether or not the guillotine was humane. During the French Revolution, it was considered humane, because the deaths occurred so quickly. Compared to their previous methods of execution, the guillotine was much smoother and quicker, which made it widely accepted. It’s strange to think that a large crowd would come see something like this. Today, this is definitely considered inhumane, especially in the United States. We have much easier and cleaner methods to execute an individual if deemed necessary.

I decided to do some looking into Broca’s area and brain areas in their relations to function. I really like the idea of studying humans with brain injuries to learn about localization of brain function. Since we cannot test on humans like we do/did on animals I think this is a very smart way to learn about the brain. Broca was one of the first to lead the way in mapping the human brain. Today we have MRIs and other technologies but back in the late 1800s and early 1900s studying patients with injuries was the best way to learn about the brain.
Paul Broca was a French neurosurgeon. His big discovery came in the 1860s when Broca studied the brain of Tan, a recently deceased patient. He found a lesion in Tan’s left frontal cortex. This area was thought to control some aspects of language. Not only Tan but also other patients with lesions or injuries in this location had trouble with speaking. Aphasia is an impairment of language ability and could be having trouble remembering words to not being able to speak, write or read. Apraxia is similar but is when someone is asked to do something and even thought they understand what is being asked but they cannot do it.
Carl Wernicke added to this information ten years later. He found that problems with the back of the left temporal lobe caused issues for understanding language. Wernicke’s aphasia is when a person can still talk and it almost seems to makes sense but it does not and can be called “word salad’. I watched a video of a woman being tested who showed signs of Wernicke’s aphasia. She could understand what the person speaking to her would ask her to do and could do actions like show how she would kiss but her speech did not make sense. She understood she was being asked to say baseball player and could repeat a b sounding word over and over but could not actually say baseball player.
We can further understand localization of brain function using Brodmann's map. Korbinian Brodmann was a neurologist in Germany in the late 1800s to the early 1900s. He was able to map the brain’s cerebral cortex. From Brodmans map we can see the frontal lobe helps with thinking, planning and other executive functions including motor control. The parietal lobe helps with somatosensory perception. The temporal lobe is involved with long-term memory, emotion, auditory perception and language. The occipital lobe helps with visual perception and processing.

I decided to explore Phineas Gage a little more. I noted in my reading blog that I wanted to learn more about him so I took the initiative in doing so for my topical blog. Phineas Gage was one of the earliest documented cases of severe brain injury. Gage was a foreman for a crew of railroad construction workers who were excavating rocks to lay railroad tracks. This process involved the worker to drill a hole deep into the boulders they were excavating and then filling them with dynamite. A fuse was then inserted, and the entrance of the hole plugged with sand, so that the force of the explosion would be directed into the boulder and not outwards. This was done with a crow bar looking tool called a tamping iron.
On September 13th 1848, Gage (25 years old) and his crew were working on the Ruthland and Burlington Railroad near Cavendish in Vermont. Gage was prepping for an explosion by compacting a boulder with the explosive powder using a tamping iron. Unfortunately, while Gage was doing this, a spark from the tamping iron ignited the powder causing the tamping iron to be propelled outward at a very high speed straight into Gage’s skull. It entered under the left cheek bone, and exited through the top of his head, later to be recovered some 30 yards from the original site of the accident. The tamping iron was approximately 3 foot 8 inches in length and 1.25 inches in diameter at one end, and weighed more than 6 kilograms.
Interestingly enough, Gage was able to regain consciousness and was able to walk within minutes of the accident. He was then seated on an oxcart, where he was transported more than three-quarters of a mile to the boarding house where he was staying. Once at the home, he was attended by Doctor John Martin Harlow. Harlow cleaned Gage’s wounds by removing small fragments of bone, and replaced by some of the larger skull fragments that remained attached but had been displaced by the tamping iron. He then proceeded to close Gage’s wounds with adhesive straps and wet compressive pads. Gage’s wounds were not treated surgically, but were instead left open to let the injury drain into the dressings. Within days of the accident, one of Gage’s exposed brain pieces got infected with a fungus and he lapsed into a semi-comatose state. His family prepared a coffin for him, but Gage had recovered. Two weeks later, Dr. Harlow released 8 fl oz of pus from an abscess under Gage’s scalp, if this wasn’t released, it would have had fatal consequences if it had leaked into his brain. By January 1st, 1849, Gage seemed to be leading a pretty normal life.
In February 1860, Gage had the first in a series of increasingly severe convulsions. He later died in San Francisco on May 21st. In 1866 Harlow somehow learned that Gage had died in California and opened a correspondence with Gage’s family there. At Harlow’s request they exhumed Gage’s remains long enough to remove his skull, which was then delivered to Harlow. About a year after his accident, Gage had allowed his tamping iron to be placed in Harvard Medical School’s Warren Anatomical Museum, but later reclaimed it. After studying the iron and skull, Harlow then brought them back the Harvard’s Anatomical Museum, where they remain on display today.

The topic that I would like to blog about, and a topic that I had found rather interesting, is that of the guillotine. The guillotine is a contraption that interests me, because it is known as more of a “killing machine,” and the concept of it before I had researched and read about seemed absolutely horrible and inhuman. In contrast though, it was in all actuality a more human to carry out death sentences, as opposed to cutting off people’s heads with axes and having them be much more painful if it wasn’t thoroughly done. The concept of the guillotine fits along with the chapter, because it contributed with research regarding to the consciousness of people after death, and investigation of responses after decapitation had occurred in whether or not they were able to perceive pain afterwards.
The research that I had found was contrary to any of which I had previously read, and had stated that Joseph Guillotin was never the actual inventor of the contraption. Instead, he was the person that had opted for a machine that would be able to rid suffering from the victim. The National Assembly had adopted his basic idea of the machine, and had hired other people, including a harpsichord maker, to design and build it. They had first tested the machine on animals, and eventually had a death toll of over 15,000 people before the end of the French Revolution even though it wasn’t “fully invented,” until 1792. Along with common criminals that had been victims of the guillotine, there were several famous individuals who had also seen their demise with the drop of a blade. Louie the XVI and Marie-Antoinette, as well as other well-known people are included in the group of victims of the guillotine.
Although the guillotine was known to have originated in France, there were other forms of guillotine-like machines in other countries. There was the Luxemburg guillotine, the “Nuremburg” guillotine, the Metz guillotine, Butzbach/Mainz, and the Leige guillotine are just a few examples of how different countries made their own versions and adaptation of this machine.

Edward Hitzig is known for his work in neurophysiology. His research partner Gustav Fritsch had experience in physiology and anthropology in a slew of countries. But in 1870, the two began to probe the cerebral cortex of a dog only to discover the importance of the cerebrum.
The research began in a military hospital in the 1860’s, Hitzig began experimenting on wounded soldiers with pieces of skull missing. Using a wires connected to a battery, he began to probe expose brains with the weak electrical current. This first results he saw the eyes of the unconscious patients move when he probed one area, an not for another. From this he concluded that the region of the brain more associated with motor functions in the front, and the farther back was not.
When 1870 rolled around, Hitzig enlisted help from Fritsch by creating a makeshift laboratory in Fritsch’s home. Instead of human subjects, they began research on live dogs. Using a scalpel, they removed the “forepaw” area unilaterally on a few dogs. This impaired the postures of the dogs, or were seen as “abnormal”, but left the sensation of the dog relatively in tact. This lead Hitzig and Fritsch to conclude that they had found a region of the brain that controlled motor skills. They called this region the “motor strip”, which is located back area of the frontal lobe in the cerebrum, which we know now as the motor cortex. They found 5 areas of the motor strip that controlled different muscles of the body, those being the neck, anterior leg (extension), anterior leg (flexion), posterior leg, and face.
Through this research, the two also came across another crucial element of brain anatomy. When one hemisphere was stimulated, the opposite side of the body exhibited a reaction. This is a concept that most people learn in middle school, but it’s still an critical discovery to understanding the localization of sensation and motor of the brain.
Their contributions to localization testing of the brain led to the discoveries of many other researchers of the neuroscience. One of their successors also experimented on animals, David Ferrier localized the motor functions of monkeys as well as sensory regions.

The topic I chose this week was The Clinical Method in psychology. It fits into this chapter because this chapter was all about early research on the nervous system and the clinical method is a way to study human brain function, which the brain is apart of the central nervous system. I was interested in this topic after reading the story of Phineas Gage. Gage was a railroad worker who survived a very severe head injury. During work a tamping iron flew up in the air and entered his head below his left eye, went through his head taking much of his frontal cortex and exited his head through his forehead. What really makes this story interesting and remarkable at the same time is Gage was not only survived but was able to live on his own. Even after the accident at the doctor’s office, he was able to communicate with others. However, Phineas Gage was not entirely the same person he was before the accident. The brain injury changed his personality and behavior dramatically. His friends stated it was “no longer Gage”.
Paul Broca is generally credited for developing the clinical method. Broca was a French physician, surgeon, anatomist, and anthropologist. However, Broca is most known for his work and research on what is now known as Broca’s area. This area is a region of the frontal lobe of the brain. However, Broca had lots of work with the brain including the clinical method.
The clinical method is generally used by clinical psychologists to study individuals with mental or behavioral problems. It can also be used to study the brain after something traumatic has happened such as a stroke. When studying individuals with mental or behavioral problems, the main goal is to detect and diagnose their particular problem and try to find the best way of treatment. This method can be used when trying to understand the causes or people’s fears, anxieties, worries, frustrations, obsessions, and their emotional, social, mental, and educational problems. Back in the 18th century, people were not able to study the brain until after the person was dead. With today’s technology, however, we are able to examine the brain without harming the person. By knowing what each part of the brain does and how it affects the body we can better help people who suffer from brain damage. We can inform them what will happen to them. Whether it be memory loss, not being able to recognize faces, etc, etc, we can help them cope. We can also better understand that they may not be the same person or act the same as they did before the brain damage.

After reading Chapter 3, I decided to further search ablation. Ablation fits into the chapter, because Pierre Flourens set out to disprove phrenology with the technique called ablation. I find this topic interesting, because it is so unique, and I want to learn more about ablation.
Brain ablation was first introduced by the surgeon, Pierre Flourens in the 1820’s. Flourens opposed Gall’s beliefs in phrenology, and set out to obtain experimental evidence disprove it. Ablation is the process of the removal of a part of the brain in order to determine the function of that part that was removed. Due to the inhumanness of the procedure, Flourens used rabbits, birds, and dogs in his experiments. Flourens started the process of ablation by first putting the animal under anesthesia and preparing it for surgery. Next, he drills a hole into the animal’s skull. To reach regions deep inside the brain, he would use a device called a stereotaxic apparatus to insert an electrode. Flourens produced electrolytic lesions by passing an electrical current through the electrode that produces heat and destroys the desired part of the brain.. After a few days the animal recovers from the operation, and the researcher can assess its behavior. After the animal’s death, an investigator can remove the animal’s brain from the skull, slice it, and examine it under a microscope to determine the true extent of the lesion.
Although ablation is highly invasive, it does have its advantages. The clinical method, where psychologist study the behavior of patients with brain damage and then study their brain upon their death, may take many years to obtain research on. On the other hand, ablation can be done quickly in a matter of one day. Also, by ablation, you are able to see an exact correlation between parts of the brain and specific behavior, because the surgeon of stimulating the brain with an electrode that can cause an immediate reaction. A downfall of this experiment would be the obvious ethical issue. I’m sure that if this were to be done today, PETA would not be thrilled. Another thing is that we can never be sure that the effects that animal participant would be the same to that of a human.

The topic I found very interesting in chapter 3 was the work that Gall and Spurzheim did with location of functions in the brain and also phrenology. This chapter was primarily about the roots of neurology and how the brain relates to psychology. It also opens many doors to surgery and medical roots to future years and doctors. I believe this is such an interesting part because it is so bizarre that this hunk of mass in our brain is one of the most complex things in existence and it also has so many key functions and is really the most important organ in the entire body and without it we would not be a sophisticated species.
Franz Josef Gall was the father of phrenology which is the study of the brains shape affecting emotions or one’s self. Gall believed that people that have similar shaped heads behaved the same way because their brains would be similar. He also realized the idea of localization of function which was the basic idea of today’s work on the brain. He was also among the first to really classify the brain as an organ and to control both motor and emotional control of the body. He was also noted at finding that each side of the brain is different functions called contra lateral function which is the concept of one side of the brain controls the opposite side of the body which was quite revolutionary in itself. Johann Spurzheim was an avid follower of Gall who was responsible for popularizing phrenology after breaking off from Gall and his work to do his very own work with the brain and its functions. He believed that the specific sections of the brain had different functions and believed still a lot of Gall’s theories about the brain being an organ. Spurzheim also thought the brain and its size to be a factor in an individual behaviors and more specifically emotions which he even labeled on a drawing of a brain. Both many also did many surgeries on the brain on animals and an even a few humans to better understand the brain.
The last piece website I observed was about the different parts of the brain today and there functions. I noticed how it has changed so much over time, but the main idea is that the realized long ago that different parts of the brain do different things. The two scientists gained so much information to be one of the biggest finds in science and essentially to be the major stepping stone to both medical and neuroscience.

Before reading this chapter I had no idea that the Broca’s area of the brain was named after a person. I also fund the story of “Tan” interesting and wanted to know more about Pierre Paul Broca. This is relevance to this class because Broca revolutionized how we look at language. His doings led other researchers to figure out what the parts of the brain controlled. He was a very smart and well-educated man; he entered medical school at the age of 17 and graduated when he was only 20. Broca did research on cancer pathology, infant morality, cartilage and bone, aneurysms, and the comparative anatomy of the brain. Broca was told about a patient named Leborgne, otherwise known as “Tan” because the only word he could clearly say was “tan.” Broca examined him a few days before he died. During his examination he realized that “Tan” had no loss of mental function. He was comprehensive. Broca decided from the autopsy that the patient had a lesion in the frontal lobe. Another famous patient Broca studied was named Lelong. He should say five words: yes, no, three, always, Lelo (part of his name). These words were not pronounced the best. When this patient died of a stroke Broca did an autopsy of him as well. He found the same problem with Lelong’s brain that he found in Tan’s brain. After this found evidence to support his claim he found more in 11 more cases over the next two years. He presented his findings to the Anatomical Society of Paris and the Anthropological Society. Both groups were excited and supportive of his research about localization.
An aphasic patient is a person who has speech and language disorders that happen because of brain injuries. Another way to think of it is that these patients know what they want to say, but they can’t get the words out.
Today we have technology something Broca didn’t. MRIs and fMRIs are able to give us more a detailed look at the brain and what is going on. We also do not have to wait for the patient to die in order to take a look at their brain with an MRI or fMRI. The brains of Tan and Lelong have both been preserved and were used to study the Broca’s area more thoroughly. From MRI studies researchers have found that the Broca’s area is responsible for various language types of tasks. More interesting is that if a patient has a brain tumor slowly destructing the Broca’s area their speech is still pretty well intact. This makes researchers believe that the functions of the Broca’s area can be moved to nearby areas in the brain, maybe even the homologous area in the right hemisphere of the brain. The lesions found in Tan and Lelong were deeper into the brain than just the Broca’s area. Language and cognition are extremely complicated and even more than what we used to think.

I wanted to research the nervous system. I read all about it in this chapter of the book and it got me interested in how the muscles twitch after decapitation. There was an argument that there was consciousness in things that were decapitated because they moved slightly after death. After many researches, Wytt found that the spinal cord was the main thing for movement in our bodies. As we talked about in class today, the same thing happens with chickens. Some chickens can even run around for minutes before actually dying. As I went to research this, I found a youtube video and Rigleys believe it or not video showed up. A chicken got his head cut off but still had brain tissue that survived the cut. The owner then was feeding it through a syringe and it lived for 4 more years. I thought that was so cool. A headless chicken survived a cut and lived for four years! How does that occur? This obviously branches far from the initial research, but was cool and out of the ordinary when thinking about what should happen when something gets beheaded. An article I read said that it’s not IMPOSSIBLE for them to have consciousness, which is actually against what our books and those studies say in the book. this article read that many were asked before they were beheaded to blink and it was witnessed on numerous accounts that there were blinking to up to 30 seconds after decapitation. Is this completely wrong and just witnesses were lying? The author of this text said that it is not impossible to not lose consciousness but it is extremely rare. The last article I found stated that a medical consensus said that life does live on after decapitation for 13 seconds. They stated that decapitation is not what kills the body. In all actuality, it is the lack of oxygen that kills someone or something. Given how much oxygen you have in your brain at the time, is as long as you will remain consciousness after decapitation. This was extremely polar opposite of the book and was interesting to read both sides of the story. No one will ever know exactly given that each individual is different and/ or it merely is just muscle spasms.

I chose this because it contradicted the book and claims that in rare occasions, consciousness still occurs

this one states opposite of the book in that oxygen kills not decapitation.
I decided to do more research on Hermann von Helmholtz. This fits into chapter 3 because he is discussed briefly on his multiple discoveries. I found him very interesting because he did so much and was involved in several fields of science.
Hermann von Helmholtz was born on August 31, 1821 in Potsdam, Kingdom of Prussia. Hermann’s father served in the Prussian army and also taught philology and classical literature. His father’s influences during school played a big role in his interests later on in his career. Hermann’s main interest in school was in the field of physics. He was steered away later on in his education by his father because at that time scholarships were only offered in certain fields and the Helmholtz’s didn’t have enough money to send Herman to school on their own. In 1837 Helmholtz was awarded a scholarship by the government in the field of medicine. He went on to attend the Royal Friedrich-Wilhelm institute of medicine and surgery in Berlin. Helmholtz graduated from the institute in Berlin in 1843. Upon graduation he was assigned to a military regiment which was required for him to receive those government grants. During all of his spare time he spent researching in the field of mathematics trying to solve a few theories that he had. In 1847 he published a paper on his findings on the study of muscle force and where in originated from. He proposed that there were both chemical and physical properties involved. He believed that if there was a certain force involved then perpetual motion would be possible. Perpetual motion is motion that continues indefinitely without any external force of energy. He later applied the idea of conservation of kinetic energy. He believed that in situations when energy appears to be lost is rather converted into things such as heat energy. His main goal was to demonstrate that no energy is lost during muscles movements. A good quote from Helmholtz to describe his research is “A moving body whose motion was not retarded by any resisting force would continue to move to all eternity”.
Hermann also provided a simple demonstration of nerve impulse speed and how it worked. This theory became one that we still discuss today, reaction time. This is still important in the modern world from athletics to driving skills. This concept although tweaked some still has great value in science today. The biggest accomplishment that Herman Helmholtz had was the invention of the ophthalmoscope. The ophthalmoscope is a device that allowed doctors to look inside a person’s eye and see the details of their living retina. This was the most important invention for ophthalmologists at the time because it allowed them to be view, and diagnose eye diseases and prevent some blindness. Herman created this using cardboard, glue, and glass plates from microscopes. After this invention Hermann was able to propose theories on such things like depth perception, color vision, and motion perception. Besides doing research in the fields of physics, physiology, and psychology he was also an accomplished professor for many years. Helmholtz’s first academic position was in 1849 where he was appointed the associate professor of physiology at Prussian University of Konigsberg. Later on in his career, 1855 he accepted the job as a professor of anatomy and physiology at the University of Bonn which was in Prussia as well. His final teaching experience was in 1871 where he accepted the position as professor of physics (his first love) at the University of Berlin. Helmholtz had many great accomplishments through his career other than the invention of the ophthalmoscope. He had huge discoveries in energy and muscle movements. He also had several theories of hearing and the different varieties of color mixing. Among many awards throughout his career he was awarded a suffix to his name. “Von”. This honor is his country was similar to being knighted. Many of Helmholtz’s finding have now been disproved or expanded on and changed but during his time he was a very important multi field talented scholar that helped to improve on science during his time and discover new findings that are still used today.

This website went more in depth on his findings and gave me a lot more information on his life, background, education and personal life. It also discussed his major publications more in depth than the other websites.
The most exciting part of this chapter was the Phineas Gage miracle story. I have heard of Phineas Gage before in previous classes, but I did not know in detail of his accident. Phineas Gage should have died due to the damage of his frontal lobe. After reading his story I wanted to find out about other brian damage miracle stories of today, and I even came across a lobotomy story.
The brain is very fascinating and continues to “awe” psychology students and researchers. Neuroscience has become so popular, because understanding the brian can lead to cures and solutions.
I found one very good Youtube video on Phineas Gage brain and it shows his skull from the Harvard Museum, a cheerleader living through a gunshot injury in her brain, and Rosemary Kennedy’s lobotomy.
The first source showing Phineas Gage’s brain was remarkable. The video shows the skull and damage to his brain and tells how he should have died. The textbook also went into detail that he walked himself to the doctor’s office and even talked to people after his accident! I found this to be such a visual miracle to see the actual skull and indentions from his accident. This particular demonstration ties in with the chapter discussing the brian and neuroscience. Chapter 3 is mainly discussing the brain and how it functions, and who found certain discoveries. Gage’s miracle story is one of the most popular miracle stories of all time. I think this is so interesting because many people would not live if that same incident happened to them, especially in that time period. I love learning about the brain and this video was so intriguing.
The second article from the ABC news tells a story about a cheerleader named Rachel Barezinsky, that had a gunshot wound to the brain. I thought this was very interesting because this only happened in 2006, and is another miracle story of a brian damage survivor. The story stated that mortality from gunshot wounds to the brain are very high, around 90%. The fact that accidents are still happening in today’s society only shows that these miracle survivor’s can happen in any time period. However, I believe that through the technology in the modern world vs. Phineas Gage’s time period, Rachel was able to live. Therefore, if this happened to someone in Gage’s era, would they have survived? I have mixed feelings about that question, but I think anyone that survives such a tragic event, is very fortunate.
The final article I stumbled upon was the death of Rosemary Kennedy. I have always loved the Kennedy family (since they are American royalty) and I was so shocked to find out that she had a lobotomy. I wanted to research lobotomy stories because I think those procedures are very tricky and rely on a lot of trust in the surgeons. Lobotomy is when the frontal lobe’s of the brain are scraped away, and they thought this would help Rosemary’s mood swings because of her mental retardation.
However, the article did not state whether it worked/helped with her mental mood swings. I thought this was interesting because psychosurgery was in its infancy at the time and not many people received lobotomies. This particular story ties in with chapter 3 in discoveries on/ and of the brain. Rosemary was said to be one of the first people to receive a lobotomy with mental retardation. The chapter was mainly focused on experiments on brain damage, and "what caused this" in the brain.
Moreover, these three miracle stories have changed the way people view brain damage. Phineas Gage survived a horrible accident without proper technology, Rachel experienced a gunshot wound that would have killed her, and Rosemary underwent a dangerous surgery to “cure” her mental state.
The brain has always been so interesting to me and this chapter really focused on neuroscience and how experiments in history have shaped technology in today’s world. The three stories are proof that miracles do happen, even in extreme cases, no matter the era.

After reading chapter 3 I found the discussion on Phineas Gage to be the most interesting. I find it interesting because a large pole can go through a man’s head and the man, within 2 months, is pronounced recovered. Of course he did suffer from a drastic personality change and did eventually die from severe convulsions. Obviously something was tampered with his brain that took years before it affected him at all. Gage’s skull was relooked at and studied to look deeper into what actually happened to him; there are many controversies over what actual damage was done to his brain. They found out that it passed through the anterior frontal cortex and white matter, but it has not been determined whether the lesion involved both frontal lobes or was limited only to the left side. The whole accident has had a lot of advancement toward the field of neurology; evidence now suggests that damage to the frontal lobes could alter aspects of personality and affect social skills. Before this incident happened the frontal lobes were thought to have little role in behavior. There was also a good discussion on the three places that Gage’s skull was damaged, where the pole entered (cheek bone), behind the orbit of the eye, and when the pole exited (top of head) which was the largest. The exit wound was the largest and actually never healed, and the circumference of the exit hole is bigger than the circumference of the pole, it is difficult to determine exactly where the iron pole exited his brain. So I guess a question of mine is if they don’t know exactly where the iron pole could have exited his brain how can they study the whole accident down to the point to why he experienced such drastic changes?

After reading chapter 3, I was interested in the topic of localization of the brain, particularly Flourens method of ablation. This fits into the chapter because finding out which parts of the brain do a specific activity can better help scientists and psychologists find answers to questions they have about humans and other species. I’m really interested in this because in almost every other class I am in, we are studying the brain and it’s functions as well. Also, the brain is something we all have and if I know how it works, I can better understand people and be more knowledgeable in the field of psychology.
When Gall’s theory of phrenology was introduced to the public, there were many critics. Jean Pierre Flourens was among one of the biggest critics. Flourens was a French psychologist that used the method of ablation to study the brain and its specific functions on animals such as hens and pigeons. Ablation, or the surgical removal of specific area of the brain, was used to observe the behavior of the subject to see which area of the brain affected which function. Flourens didn’t develop this technique, but did refine it.
Flourens was able to conclude that the removal of the cerebellum resulted in the loss of coordination meaning that it regulated and integrates movements. The medulla controls vital functions such as circulation, respirations, and general body stability. He was able to conclude that the cerebral hemisphere is responsible for higher cognitive functions.
A large point that Flourens made was that it was not so much the location of damage that had the largest affect on the subject, rather than the amount of damage that was done. Another big observation that he found is that if there is enough brain tissue still intact after damage to the brain, the remaining tissue will essentially take over the function of the missing area.

Phineas Gage is revered as one of neuroscience’s most “famous patient”. As we learned in our reading, Phineas Gage was a foreman for a railroad crew. He was working on a railroad in 1848 when a tampering iron pierced his skull just under his left eye and went through his brain. To everyone’s surprise, Gage did not die. In fact, he was conversing with the doctor only 30 minutes after the accident. Although he could no longer see out of his left eye, he was able to live independently. Soon afterwards, everyone that once new the “old” gage, who was creative, intelligent, and hardworking, met a “new” gage. For an unknown reason at the time, Gage took on an entirely new personality. He could no longer keep plans; he would use excessive profanity; and no longer had respect for fellow human beings. Not long after these changes were noticed by his friends and family, his employer noticed the difference. Gage, who was once the foreman of the railroad company, was not allowed to return to work. After this serious blow to his career, he took on a new path driving horse drawn coaches in Chile. Later, at the young age of 36, Gage died in San Francisco with his family after a multitude of seizures. So, the question is, what does this guy have to do with Psychology?
Well, as you can probably suspect, the reason for his sudden change in personality was due to the brain damage he suffered from the tampering iron. The reason that Gage is famous in Psychology today is because he was the first KNOWN case of brain damage and personality change. We still see the same things happen in today’s world, even if it wasn’t as extreme as a tampering iron piercing through the skull. Take one example which I have researched. A 12 year old boy who was always regarded as “respectful, caring, and compassionate” by his family and educators suffered a terrible car accident. The weird thing about this case is the boy has an I.Q. of 128, which is respectable, but since the accident he has become extremely violent. The violence has gotten so out of hand that the boy has been expelled from three different schools. The cause of this: damage to the frontal lobe.
While researching this topic, I ran across a quote that I believe NEEDS to be shared. “ Yes, they are all injuries to the body, but only those touching the brain have the capacity to change the "soul" of a person.” How can damage to such a small area of the body have so much effect on WHO a person is? Let’s touch base on some neuropsychology. The Prefrontal Cortex is the area in which the brain carries out every day psychological functions. This includes, but is not limited to: personality expression, decision making, and monitoring social behavior. Take another example: A 23 year old male that had a tumor removed from his right frontal lobe at the age of 3 months. By the time this individual was 9 years old, he showed little emotion, had extreme anger issues, and also lacked motivation. As he progressed through his teen years, he had poor study and work habits, did not groom himself properly, lied often, had barely any friends, and showed absolutely no remorse or guilt for his actions.
All of the signs seem to point in the same direction: lying, stealing, lack of emotion, anger issues, and fighting. The weirder part about this phenomenon is that in previous years, (1940-1950s) damage to the prefrontal cortex was INTENTIONAL. A prefrontal lobotomy, which is the severing of connections to and from the prefrontal cortex, was a quite common psychosurgery. In 1951, over 20,000 prefrontal lobotomies were performed in the United States. Prefrontal lobotomies were performed on patients with severe mental illnesses. Prefrontal lobotomies basically would turn people into zombies, and luckily due to the invention of the antipsychotic drug chlorpromazine, prefrontal lobotomies gradually died in the United States. Although they still happen, they are extremely rare.
The research that I have conducted regarding this issue has opened up my eyes to a very morbid reality. A simple car accident could change ME or someone I know for the remainder of life.

This website was great for giving me a deeper background on Phineas Gage than the brief description that the book gave.
I will also admit that I dabbled with Wikipedia mainly to explain some of the terms that I was not familiar with.
I wanted to learn more about Phineas Gages’ accident and how it affected his life and personality after the accident. This topic fits into the chapter, because the chapter talks about the brain and its functioning. It also talks about brain damages and told about Phineas Gages’ accident, but I wanted to learn more about how it affected him. I am interested in this, because I love learning about the brain and how it works, as well as how different types of damages affect the brain, and Phineas Gages’ accident caught my attention. I had heard about it previously in high school about how the iron went through his skull and wanted to know more.
Phineas Gage was a railroad worker and while working one day, he and the rest of the crew were getting ready for an explosion to break the rock to make a railroad path. On September 13th, 1848, while getting this ready, there was a spark from the tamping iron and it ignited the powder. The tamping iron went right through his skull from the bottom of his left eye and exited the top left of his head. A part of his left frontal cortex was taken with it. Gage was one of the first reported cases of severe brain injury. It was said that this tamping iron weighed 13 ¼ pounds, and landed around 30 meters away. Gage gained consciousness within a few minutes and was walking. From September 23rd to October 3rd, Gage was semi-comatose because of the pressure on his brain. His friends gathered and had a coffin ready because they expected his death. A few days later Gage was able to get up and take one step. About a month later it was told that he was walking around the house and could walk up and down the stairs. April 1849 he returned to see his doctor who said he had loss of vision in his left eye and “partial paralysis on the left side of his face.”
Gage no longer was able to work at the railroad after his accident, but still worked. He worked in a livery stable for a while and then for years worked as a stage coach driver. Gage started to behave inappropriately in social situations and started to use profanity a lot and wasn’t very respectful. His friends said he was no longer the same Gage.
In February of 1860 Gage started to have severe convulsions. Gage died May 12th, about twelve years after his accident.
I found it amazing how he was still able to do some work after his accident, and that he lived just about twelve years with this brain injury. According to the readings I read his personality changed and he “wasn’t the same Gage.”

The topic I chose to research more on was the neuron theory. I am interested in this topic because the neuron theory is at the base of reflex, thinking and conscious movement. The neuron theory fits into the chapter because it the last piece of the puzzle to explain hos signals get transmitted from one part of the body to the other. The neuron theory is, as far as we know yet, the final stage to understanding our nervous system.
A neuron is a nerve cell in the body. Very basically it is composed of dendrites, a nucleus, an axon and axon terminals. The job of a neuron is to relay messages to other neurons through synapse. How synapse occurs is once a dendrite is stimulated it releases ions. These ions travel down the axon and through the axon terminal where they release a chemical or electrical charge that excites the dendrites on the next neuron and the scenario repeats itself. Sir Charles Sherrington was the first to state that there was a space between neurons where the synapse happens. We now know this to be true today, but it is amazing that Sherrington discovered this without ever actually seeing a neuron. We now know today that there are many different chemicals that neurons use to send different messages. These chemicals are known as neurotransmitters. More and more in psychology, we see great attention being paid to neurotransmitters. Neurotransmitters are at the basis for psychiatric drugs used to treat mental disorders like schizophrenia, depression, ADHD and many more. Not only has our understanding of neurons helped us to treat psychological disorders it has also made a large impact in other fields of science. Creating and understanding drugs that help in physical human performance have come a long way as well. Drugs like caffeine are now regulated by the NCAA to make sure that athletes do not gain unfair advantages over their competitors.
Even though we have come very far in understanding our nervous system, starting with experiments with spinal nerves to how messages are passed through the nerves by synapse, there are still advancements to be made. Improvements with psychiatric and performance helping drugs, to lower the degree of adverse side effects people experience. Even when it seems that we could be at the edge of figuring the human body out our imagination helps us dig deeper and with advancements in technology I am excited to see how much more we can learn about the human body in my lifetime.

One of the people I found interesting in this chapter was Phineas Gage. I knew the basic story to his injury but I wanted to find out a little more detail if I could to his personality and what the rest of his life was like. This topic fits well with chapter 3 because Phineas Gage was a sort of marvel for that time. It was unknown before that with such an injury that not only could someone survive, but that they could still function in everyday life and even work. I think it is interesting to see how someone that people thought so highly of could have such a change in personality that he was no longer enjoyable to be around.
I discovered in a video on Phineas that after his accident and after his life began to change he decided to work with horses on a horse farm. It wasn’t long before he couldn’t handle that anymore either and he began to work as an attraction for Barnum’s Museum in New York City, where people could come and see him in a tent while he posed with the iron that caused his fate. It must have been pretty difficult to go from someone that was respected and well liked in the community with a steady job, to a circus attraction across the country.
There seems to be a lot of debate and confusion between historians and different authors on Gage’s personal life post accident. Some books claim that he abused his wife and children after the accident, but in fact Gage was not married and did not have any offspring. One source even went so far as to say that he at one point sexually molested children after his accident. There is no evidence to support those claims and those that had been in touch with Gage’s family and friends received no such report on that behavior. Something I did find that I thought was extremely interesting was that in 2008 a report of Gage’s public appearance and a report of his life in Chile for some time had been discovered and from what could be understood from the material, it seems that he was eventually able to readjust himself to his surroundings and was able to learn how to behave appropriately in society again.
From what we can see of Harlow’s descriptions of Gage, he is never described as a drunk or molester. The last almost 12 years of his life were not closely documented, even his date of death has been told to be off a year from one account to another.

I started of my search wanting to do my research on the popular culture of phrenology, but I was able to find only small amount of information on that subject. With that, I opened up my search to the whole study of phrenology, but tried to emphasize the ideas of popular culture in phrenology that I found in my writing. In 1796 Joseph Gall, a physician in Germany began talking about the individual functions of the brain in terms of organs, he called it organology. Not long after he began lecturing on the idea of organology he changed the term to craniology. Then finally, a collegue of Gall’s by the name Johann Surzheim would introduce the term phrenology, which would stick. However, all of these terms really mean the same thing. Gall had come up with the idea that the brain had 27 organs, each of which had their own function. He believed, that like a muscle, the parts of the brain that were used more would be larger and so the skull would be larger over those part of the brain. Then in return by feeling for bumps in the skull one could discover the character traits of a person.
In the very early 1800’s phrenology spread from England to America, where it would thrive better than any other place on the globe. Although it cannot be proven why this so, it is speculated to have happened for many reasons. At the time of its arrival Andrew Jackson was the president and with that came the ideas of the perfect society, common sense and a sense of individualism were instilled in the people of the time. Phrenology helped to further instill that these principles could happen. With the study it we were capable of discovering the characteristics of people and if the person did not like who they were, phrenology allowed for them to change that with the “exercising” of the brain. This idea that we can change the size of the organs of the brain and in turn change people and society as a whole may have given them something to look forward to, a perfect society. Another reason why phrenology flourished in America may have purely been the lack of a national religion. For other nations phrenology was shunned altogether by the churches of the nation, because of this phrenology was not allowed to spread like it did in America. The final reason why phrenology was so well accepted may have been because of the lack of adequate medical care in the United States. At the time of its arrival medical care was so poor, that sick people would take the risk of traveling to Europe to get the treatment they needed instead of taking of the risk of dealing with the dirty conditions, unwell trained doctors, and just harsh conditions of the medical field in the United States.
As I wrote about before, people wanted to use phrenology to create a better society. This came about with the idea that the science could be used on prisoners if there was prison reform. With a restructure of prisons many believed that it was possible to change the way criminals think because of the study of phrenology. Previously it was believed that harsh treatment and penalties for prisoners was the way to make them productive citizens again, but after the introduction of phrenology people began to think that criminals were incapable of moral and ethical choices and the only way to “fix” them would be to alter their brain and the way they think.
Another topic of phrenology I would like to mention is the business of phrenology. After the introduction of the phrenology, many people saw a business venture and began to sell services to people all across the countryside in the United States. Phrenology became so commonplace that many employers began to ask for a phrenological report for a phrenologist when hiring someone to make sure that the person was honest and a hard worker. Two of the most famous phrenologists Orson and Lorenzo Fowler were not only businessman, but also created and entire business based around the study. They toured the country-side doing readings and offering advice to people on possible relationships, marriages, and self-improvement methods. Not only did these men commercialize phrenology, but they defiantly contributed the spread and acceptance of the study.
For me the biggest thing that we can take of the culture and study of phrenology is that we have to start somewhere, sure it is true that today we know phrenology is a pseudoscience and seems completely ridiculous, but that is what makes the study of it so interesting. For some people they think of being wrong as a bad thing, but without being wrong we can never become right. I think that in today’s culture people are so scared to be wrong, that many times they are afraid to step out on a limb and say that crazy idea, but who knows that idea may just be the next great innovation our discovery. We as a society have to remember to keep an open mind and nor shut out ideas just because they may seem crazy, because if someone proves that idea wrong than we are that much closer to the truth.

I found the work of Paul Broca to be very interesting. In many articles about his work he is referred to as well before his time. He is known for realizing that the brain has different sections controlling specific things such as vision, language. His case with the patient “tan” was amazing in that he correctly identified that speech was affected in a particular area of the brain. The work of Broca fits in with how the physiological side of Psychology has grown and developed.
Broca studied two patients who seemed to be of normal to high intelligence but yet both had issues with their ability to communicate effectively. Broca determined that it was because of injury in a particular portion of the brain which is responsible for the control of language and communication. This is still referred to by many as Broca’s area. As I searched the work of Broca it seems that he also was an early forensics scientist as well. He correctly identified the injuries of ancient skulls as had been damaged due to a procedure called trepanation, which the skulls of living people were bored into in a rough type of surgery.
Broca was also a man who thought for himself. He considered himself a Christian but he also did not take everything the church leaders spoke as truth. He believed in the theories of Darwin. As a person who holds some very conservative beliefs myself but has also bucked some of the authority of outdated ideas in some leaders of the church, I greatly respected his courage. He was also a humanitarian and was concerned for the health of the poor. I began this search mostly about Broca’s work in the brain but in the end I found his entire life fascinating and noteworthy.
This is a side note in the reading of trepanation practices. I found it interesting that while in Europe people tended to be killed from these surgeries when they were performed in South American countries many people survived the surgeries and lived several years. The readings I found cited the poor conditions in the overpopulated areas of Europe in comparison to the open spaces and use of herbs for anesthetic in places like Peru.

From the material in chapter two the topic of interest I chose was Phineas Gage and what effects brain damage can have on personality. I thought this would be an interesting topic to research because the Phineas Gage story is so unique – to think that a horrendous accident could end up teaching us so much. Cases of brain injury and observations regarding behavioral changes even now have a huge impact on neurology and give information on how the frontal lobes affect personality. Before the study of cases such as Phineas Gage the frontal lobes where thought to have very little to do with personality.
I believe the topic fits in this section because it describes how the frontal lobe affects personality and this chapter discusses the brain (localization of brain function, effects of lesions, etc...), in depth.
The studies linking brain injury to behavior change are interesting because, while we think of the brain as allowing us to think and reason, we don’t as often realize that the brain is what makes our personality possible as well. A dramatic event like the explosion that drove the rod through Gages’ brain is one example of this. But so are everyday events like consuming alcohol or too much caffeine. These can change our personality as well, because the drugs change something about our brain. Today, there are more powerful ways to study how these changes might be localized in the brain. For example, not just x-rays, but the modern techniques of CAT scans, PET scans, and MRIs can “show us” what parts of the brain are turned on or off by a particular drug or by a particular task. The structure (hardware) of the brain and its relationship to personality (software) seems central to the “science” of psychology.

The most interesting topic that I chose to do more research on was Phineas Gage. His story fascinated me because not only did he survive iron going through his frontal lobe to begin with, but as a result his personality seemed to change. This story fit into chapter three because it was focused on psychology as a science, which includes the human mind. Gage was a railroad construction foreman who fell into some bad luck when preparing for an explosion. The tamping iron that he was using to compact explosive charge in the barehole sparked and ignited the powder causing the tamping iron to shoot through his head. After miraculously surviving, Gage’s personality changed and he seemed almost as if he lost any inhibition. But even though his personality seemed to have changed, some people still question if any of the changes were significant enough to be caused by the brain injury. Before the incident, Gage was seen as a good hard worker who was outgoing and efficient, but after he seemed much more irrational and even angry at times. It was as if he was a child now and lacked maturity. The affects of Gage’s brain damage can be summarized as a complete loss of social inhibitions, but technically all that can be known for sure is just the damage of the skull. Whether the rest was physical in his brain or psychological, his behavior changed after the brain injury.

The topic I chose to get more research about was reflexes in relation to Magendie and Whytts’ findings. This interested me because just hearing they did observations on decapitated heads and how they might still have some control over the body even after separated. I have heard of peoples’ bodies twitching after they die, but I didn’t put a lot of effort into going into the why aspect of it.
Whytt contributed a lot of knowledge to the reasoning behind involuntary moments of the body, after being separated from the head by decapitation. He went above and beyond in figuring out how to make muscles twitch in the leg by experimenting on tampering with nerves in near the spinal cord. He discovered that once the connection between the spinal cord and appendage, there was no reflex.
Charles Bell and Francois Magendie branched off of Whytt’s work later on and focused on the spinal cord and its functions. Although they both contributed in the studies of discovering the functioning of the two main nerve tracts in and out of the spinal cord, Magendie’s work was documented. Magendie used a live dog for his experiment. In this experiment he showed its spinal cord and the severed posterior nerve tract. The dog could still move its legs, but felt no sensation. He eventually found that the efferent anterior nerves controlled the moment while the afferent posterior nerves controlled sensation. Bell’s work ended with a very similar result. Fortunately, they both got credit by naming this discovery the Bell-Magendie Law.

My topic is Phineas Gage. More specifically, I am interested in the specialization of the various parts of the brain. I want to know about how damage to specialized parts of the brain effects our thoughts, actions, and comprehension. There are many things that we don’t know about the brain or its ability to adapt and recover over damaged areas. I don’t know anything in science that is more interesting to me than the recovery and normative functions of a brain-both in normative circumstances and in cases of severe damage. The focus on cases where individuals went through incredible damage to specific parts of their brain, yet continued to live (second video-after the PBS info.).
Phineas’ case was nothing shy of a miracle. Interestingly enough, Phineas is not alone in his extraordinary ability to survive brain trama. If you was my second video (refrenced above) you will be able to see many other examples of people who had similar experiences, but still recovered.
This summer, while I was doing my research in Taiwan, I got a small glimpse at the specialization of a specific part of your brain and how it effects your reasoning. In an experiment entitled, “Risky Choice”, we tested how the hamygdala and the dopamine produced there effect a rat’s ability to reason. It suggests that not just the location of the brain, but also the specific chemicals produced there are what changes our characters after head trama. I enjoyed studying a specific part of the brain and I found it to be an amazing opportunity for me in the field of research. Now as I look back, I realize how grateful I should be for the fact that Harlow and Phineas created a rise in curiosity and brain specialization studies as a result of the accident.
In my exploration of Phineas and related topics, I am happy to have found so many similar and equally amazing options. The one thing that I will say about the research and knowledge in this area of study is that it seems to suck. We have all of these different cases. However, we can’t set them up in a lab setting. Also, they are all very different and they don’t necessarily reflect each other. We also can’t create a lab situation like this and it’s very difficult to study how people differ with brain damage. This lack of research is most likely a result of the fact that we can’t continue to do these experiments on humans. Additionally, we usually-in experiments- have some data collected about the subject before the experiment. As nobody expects for some accident like this to happen to them, people do no have good accounts of information about themselves or their character prior to the accidents. It’s difficult to study brain specialization. Still, I enjoy the subject and the challenge and I am impress by all of the individuals I learned about as researching this topic.

Also, Phineas’ case gave way to the overarching idea, though it supplied little valid information on its own (little was known about Phineas prior to the accident).

After reading the chapter and doing the assignment for Tuesday, I was very interested in the guillotine, but more specifically, how the body still twitches after someone is decapitated. This interests me because I would think that as soon as our head is separated from our body, all connections are lost. This relates to our reading because this is a topic that was highly discussed centuries ago. Scientists studied the body/brain after it had been decapitated and searched to find answers of whether or not we were still somewhat “conscious”. Scientists use EEGs and other mechanisms to study the brain activity, which gave them the results they were looking for. I found that rat brains do in fact still produce thoughts and experience sensations for several seconds after the head is removed. Although this has not been found in humans because it is not humane to test, I would conclude that it is true for humans as well. Beheading is no longer used as a form of capital punishment, due to the fact that our brains may still be conscious long enough to know what has actually happened to us. Reports from earlier days say that the beheaded would still blink and sometimes even have eye movement after their head had been removed. It is certainly inhumane to test this theory, so further scientific research will probably not be likely. Although we cannot be certain whether or not the head is still conscious after decapitation, I think it would be safe to say that there is a high chance of it being true.

The topic from this weeks’ chapter that I was interested in and decided to do research on was phrenology. I found it really fascinating that such a study was able to create such a buzz. I was sort of in doubt about how popular it was so I decided to choose this for my research topic. Franz Joseph Gall is responsible for getting this little fad going. Gall argued that the brain is the organ of the mind and that various parts of the brain were distinct from one another. What this meant for phrenology was that different areas of the brain were responsible for certain traits that an individual supposedly possessed. This turned into a very acceptable practice of psychology and society for a period of time.
Phrenologists stated that they could tell what characteristics a person had just by examining their skulls. Greater mass in a specific region meant that the individual had more brain in that area. This could be a good or bad thing. People could possess desirable traits as well as “criminal” traits. For some, it turned out to be a good thing, but I’m sure phrenology ruined quite a few lives too. Employers actually requested and preferred to see phrenological documentation of their future employees to make sure they had the skills required for the job.
Eventually, phrenology was under fire. The problem was that phrenology advocates only believed what they wanted to, and only looked at the evidence that supported their claims. If things weren’t adding up to their expectations, some excuse was made to explain the folly. One major excuse was that the traits tended to cancel each other out. A larger brain part in one area, could either complement or cancel out a different area of the brain. Many experts realized that phrenology was flawed and set out to discredit it.
Once scientists were able to perform neurosurgery and examine people with brain injuries, it was clear that phrenology was not as true as everyone thought. An interesting fact though is that the phrenologists idea of localized brain functioning areas were actually true, just not to the extent they believed. We now know that certain areas of the brain are responsible for different functions. Definitely not in the manner that phrenology portrayed though.
I think phrenology was a very important step for the advancement of psychology and anatomy. Without the creation of this study, no one would have set out to prove it wrong. Without anyone trying to prove it wrong, we never would’ve known the truth about the brain.
