Phineas Gage Paper
The brain is one of the key role players in cognitive functioning. There are many different areas in the brain but only a few certain areas have an influence on cognitive functioning. A man named Phineas Gage showed the key elements in the specific areas in the brain that do support these cognitive functions. In 1848 Phineas gage suffered a traumatic brain injury which has aided in understanding the human brain in the fields of cognitive and neuropsychologists. This paper will help to better explain the role of cognitive functioning and the brain. One will better understand the importance of Phineas Gage’s injuries and how they have helped to aid cognitive functioning and neuropsychology.
The Brain and Cognitive Functioning
The brain plays and important role in cognitive functioning. The ability to process thoughts and information is cognitive functioning (Willingham, 2007). Learning, memory, and perception are all examples of cognitive functioning (Willingham, 2007). Different areas of the brain support different cognitive functions. The amygdala, hippocampus, and the rhinal cortex are all responsible for memory. Emotional memory and memories which are prompted by emotional behavior are all stored in the amygdala. The hippocampus is responsible for receiving information from the senses and then translating them into an individual’s short-term memory. Learned information is recalled from the rhinal cortex. “The cerebral cortex is what is studied, photographed and imaged when one begins to reference the brain” (Willingham, 2007). There are four lobes in the cerebral cortex; these are the frontal, occipital, parietal, and temporal. Each of these lobes are connected to cognitive function in one way or another.

Four lobes and the brain
An individual’s personality and ability to express emotions is due to the frontal lobe. Because of its location, people tend to think that this would be the area most susceptible to injury. The Centre for Neuro Skills (2011) explains that “there is no other part of the brain where lesions can cause such a severity of symptoms.” The parietal lobe is divided into two separate functional segments. One segment is key to sensation while the other combines visual cortex with sensory information. People with damage to the parietal lobe have a twisted view on body image as well as 3-D images (Kandel, Schwartz, & Jessell, 2000). The occipital lobe is located on the very back of the head and because of its location there is less damage done to this area. But, if these is a significant amount of damage there can be changes in the visual perception and in different fields of vision (Kandel, Schwartz, & Jessell, 2000). There are two different parts in the temporal lobe. The left side is responsible to things such as interoperating words where as the right side is associated with speech. It is shown that each part of the brain plays a very different but equaly important role in cognitive functioning.
Cognitive Functioning and Phineas Gage
When trying to understand behavior in relation to brain injury, Gage’s story has been a key case. The two doctors who oversaw Gage’s case were surprised that he was able to live at all. After four weeks Dr. Harlow, the man that recorded Gage’s recovery, noticed that he was able to record dates and times and was remembering everything (Neylan, 1999). Dr. Harlow then did further examinations and saw that gage was displaying signs of dimension and signs of cognitive damage. His character started to change and he started to be unfamiliar with those he had known the best. Though Gage’s experience was terrible, it was a critical role player in the better understanding of behavioral symptoms in relation to injury of the brain (Neylan, 1999).
Conclusion

To better understand human behavior and how the brain works, cognitive psychology must be studied. Now it is better grasped how each part of the brain plays a role in cognitive functioning and how, if injured, those different areas can change a person. This change can be physical but also mentally. Phineas Gage was an example of the great mental changes that can happen to an individual with a brain injury. Though his experience was traumatic, it has paved the way for research on brain injury.

Phineas Gage: Brain Injury

...Phineas Gage had a brain injury that allowed other researchers to learn more about the human brain and what regions affect behavior in humans. Mr. Gage was working as a foreman for a railroad when a rod when through his brain. Before his accident, Mr. Gage was “intelligent, well-balanced…modest and reliable” (Ellis, n.d.) This seems to be true because he was a man in authority, he was a foreman in charge of several men. Women seemed interested in him, at the beginning of the video, Frontal Lobes and Behavior- The Story of Phineas Gage, he was having a tussle with Benjamin over a woman. Phineas Gage’s life seemed normal and he was quite dependable. After his accident, Phineas Gage showed his emotions (justifiable or not) openly. He appeared to have mood swings, and an inability to master his sentiments. According to Carlson (2014), Mr. Gage was immature, unbalanced, reckless, and inconsiderate (p. 251). Phineas laughed a lot, cried and whimpered, and had fits of rage, all usually occurring at inappropriate times....

They considered Gage’s crew to be one of the best around. Among other tasks, a foreman sprinkled gunpowder into blasting holes, and then tamped the powder down, gently, with an iron rod. This completed, an assistant poured in sand or clay, which got tamped down hard to confine the bang to a tiny space. Gage had specially commissioned his tamping iron from a blacksmith. Sleek like a javelin, it weighed 13¼ pounds and stretched 3 feet 7 inches long. (Gage stood 5 feet 6 inches.) At its widest, the rod had a diameter of 1¼ inch, although the last foot—the part Gage held near his head when tamping—was tapered to a point. This next part has some different variations. Gage’s crewmembers were loading some busted rock onto a cart, and they apparently distracted him. One says Gage...

...Science unrolls and unravels the many functions of the brain through research, inference, experiments and actual real life occurrences. Such was the case of Phineas Gage (1823 – 1860), a young foreman on the railroad in the mid 1800’s who survived a blasting accident which destroyed a part of his brain. Documentation on Mr. Gage’s health and personality before and after the accident opened the door to the role of the brain in cognitive functions. Phineas Gage’s accident and apparent recovery precipitated the idea that there was a connection between the human brain and the personality. First, prior to Mr. Gage’s phenomenal recovery from the loss of a substantial part of his brain, scientists believed that the brain was an entire “organ”, and that all of it was needed to function at all. The incidence with Phineas’ recovery and his continual capability to function altered scientific thinking substantially. Secondly, the adaptation that he made in his personality opened further doors for studying the cognitive adaptability of the brain. According to friends and collegues, Gage was no longer Gage. Once a friendly and affable, easy to get along with individual, he became stubborn, argumentative and forgetful, unable to organize his life in a reasonable manner. He could no longer hold down a job. Phineas Gage died 12 years after a rod pierced his skull and permanently damaged his frontal cortex.

Phineas Gage

...Phineas Gage was shot straight through the head with a three-foot-long tamping iron, and survived but with brain damage. But who would have guessed how truly similar adolescents were to this brain damaged man. Adolescents and Phineas are similar in two main ways: they make decisions that adults wouldn’t, and they have frontal lobes in their brains that are damaged or not fully developed. The first way they are similar is that both of them make bad decisions. Phineas made many bad decisions. An example was was declining an offer of $1000 for a bag of rocks. The offer was meant as a kind gesture to help Phineas get back on his feet, but Phineas didn’t understand that and was very rude to the doctor who had offered. (Phineas Gage, Fleischman 19) This shows that Phineas is not thinking logically, and teens don’t think logically either. It has been proven that adolescents do not think much before making decisions, as the text claims, “...the teenager can vaguely register that there will be parental punishment later on…” (from “Are Teenage Brains Really that Different From Adult...

...Phineas Gage PSY/360 Abstract In 1848, there was a railroad worker named Phineas Gage, who was severely injured on the job. In this essay, the author will discuss the details of the accident and what it revealed about how the different areas of the human brain support cognitive function. I will also discuss the characteristics of primary memory, the process of memory from perception and retrieval and the unreliability of memory retrieval. Phineas Gage Phineas gage is known as one of the most famous documented cases of brain injury. This brain injury occurred on September 13th, 1848 while Gage was working on the railroad excavating rocks with a tampering rod in the State of Vermont. An explosion occurred on the job-site that caused a tampering rod propelled at an extremely high speed to enter and penetrate Gage’s skull. This tampering rod entered his skull under his left cheek bone and exited through the top of his head; it was later recovered with bits of brain matter and blood on it. The amazing thing is that throughout this horrific accident, Mr. Gage never lost consciousness, in fact, by January of the following year; he had started to live a normal life. However, it was noted that around this time, Mr. Gage was considered to be suffering from some major changes in his personality.

The Emotion-Reason Connection in Your Brain

...In 1848 – thanks to an unusual, grisly accident that befell a good-natured, popular railroad foreman named Phineas Gage – scientists discovered that specific areas of your brain control how you get along with people. When Gage was laying railroad tracks, his assistant got distracted and didn’t take the usual safety measures, thus causing a freak accident – an explosion of gunpowder that blew a heavy, long iron rod through Gage’s forehead. Although he survived, the flying rod removed the front portion of his brain, and Gage lost the ability to moderate his temper or impulses. Though he could still do calculations and function in his job, his life changed dramatically for the worse. Now cranky and erratic, he lashed out at the mildest provocation, appeared irrationally unable to get a grip on his emotions and no longer got along well with his co-workers. As science now knows, the ability to manage your emotions requires effective biological “wiring” between the reasoning and feeling areas of the brain, and Gage had lost that link. People are emotional creatures, so always be mindful of the role emotions play in your behavior and that of others. For example, a medical technician named Lily used her emotional intelligence (EQ) to achieve her goals. Stuck in her biotechnology job, and frustrated by the routine and lack of challenge, she got a new job running a start-up drug development laboratory. After a year or so, she felt worn down and again stuck in a rut. She ...

...Phineas Gage and the “American Crowbar Case”. Samantha Romero PY3150 Ms. Dreskin 01-01-2015 ITT Technical Institute Phineas Gage and the “American Crowbar Case” There was a man named Phineas Gage who at 25 years old suffered a severe head injury in the year 1848, he was handsome with a pleasant disposition (Guidotti, T., 2012). The accident took place on a railroad near Cavendish, Vermont where Phineas was working (Guidotti, T., 2012). Phineas poured blasting powder into the borehole of the train track but neglected to add sand, when he tamped it down with his ‘crowbar’ the bar shot out going through his left cheek, destroying his left eye and rocketing out of his skull and landing 80 feet away (Guidotti, T., 2012). This is proven to be even more impressive because Phineas never fully lost consciousness and even considering he lost his left eye completely and neurosurgery had yet to be developed (Guidotti, T., 2012). The biggest deficit Phineas suffered was reported as a drastic change in personality and character (Guidotti, T., 2012). According to Guidotti’s article in 2012 Phineas went from being known as a “reliable, systematic and hardworking” man and after the accident was said to be “impulsive, disorganized and stubborn. His language was said to be colorfully profane, although he did not customarily swear before the injury” (Guidotti, T., 2012). Since there were no neurosurgeons during this time period, his specific injury while unfortunate allowed for some documentation...

In those days blasting holes was the normal procedure to gain access to lay the railroad down. Gage was using tamping powder to drill holes with a tamping iron. He would use the iron to pack the powder in holes and suddenly there was an explosion which led the tamping iron which was now protruding from left cheek and part of the brain and hanging out from his skull (Twomey, 2010). He had everyone one of his co-workers looking at him in amazement since he never loss consciousness. The Doctor that examined Gage was amazed as well and cleaned and bandages his wounds. Phineas Gage was a well mannered person, who enjoyed working before the accident, but afterwards a vicious viral infection had done the toll and recovery was long and hard. Gage was recovering well physically, but the infection had robbed him of sight in his left eye and decreased sensation on his left face. Gage did return to laying down tracks for the railroad but everyone who knew him saw he was a changed man (Wagar, 2004).

Phineas Gage

...Phineas Gage Paper At the age of 25 Phineas Gage was a bright, promising foreman working for the Rutland and Burlington railroad in Cavendish, Vermont. As was the practice of the times, tamping powder was used to blast drill holes for the preparation of laying track (Wickens, 2005). Gage was using a tamping rod to compact the powder in the holes before detonation when suddenly a precipitous explosion propelled the rod, which was 1.1 meters long, 6 millimeters thick, and weighing 6 kilograms, through his left cheek and brain, exiting out the vault of his skull (Leach & O'Driscoll, 1998). Surprisingly, Gage remained conscious on the ride to the doctor. Once there, Dr. Harlow, the attending physician, bandaged his wounds, which bled for an additional 2 days. Gage showed no obvious, immediate mental deficits, but an aggressive viral infection set in at the damaged area which led to a month of semiconscious recovery. The infection finally abated and Gage made a complete recovery, except for blindness in his left eye and weakness in the left side of his face. However, upon returning to work it became quite clear that Mr. Gage was not entirely himself. The damage to Gage’s brain was localized in the ventromedial prefrontal cortex; nevertheless, in order to understand the personality changes that Gage underwent after his recovery it is necessary to first examine the underlying neurological and cognitive interplay thereof.

...Psy 260 May 15, 2011 Patricia Adesso Phineas Gage The brain is most complex of all of the organs in the body. The brain is the place where emotions, perception, planning, memory, action, thinking, learning and language, among other things, all take place. Cognitive functioning takes place in the cerebrum, the largest part of the brain and is carried out by neurons. The brain is made up of thousands of neurons that are responsible for carrying messages from the brain and into the body. These neurons interact with one another by releasing a neurotransmitter that fits on to the receptor of a neighboring neuron. When the receptor is triggered in the brain it causes the body to react, act, think, feel, learn and so forth. But how does this actually work? Brain imaging has given us some insight to answer this question. Brain imaging like MRI’s, CAT, and PET scans all help in discovering the brains role in cognitive functioning. Advances in imaging technology have helped researchers pin point which areas of the brain are responsible for thinking, learning and memory. By recording activity of the brain in action, researchers can examine the systems of brain regions that participate in different cognitive functions, ranging from basic sensory and motor functions to complex functions like reasoning and language understanding. According to the Center for Neural Basis of Cognition (CNBC) at the University of Pittsburg “To discover how brain cells actually support cognitive processes...

Phineas Gage

...Phineas Gage was a foreman for the construction crew on the Rutland and Burlington Railroad in Cavendish, Virginia. He was working on the railroad using a tamping iron to press an explosive powder into a rock. This was a normal practice for blasting away rock during the middle 1800’s. While Phineas was tamping the rod down into the rock, the iron hit part of the rock and sparked, thus igniting the powder inside the rock. This caused a blast that projected the iron rod into his left cheek and brain, then coming out the top of his skull. This did not kill him; it did not even seem to have affected his brain in a major way at first. Phineas developed an infection that had him in and out of consciousness for two months, was blind in his left eye and experienced weakness in the left side of his face. Only when he returned to work did his coworkers see the change in his personality. (Wickens, 2005). This led people to study his case and do further research on neurological and cognitive studies about how his brain was affected by this accident. The initial thought that Gage was unaffected by this accident proved to be wrong. The physician, Dr. Harlow, that tended to Gage immediately after his incident hinted that while he did not seem to be affected intellectually, he had observed changes in his personality (Kihlstrom, 2010). This shows that neuroscience and social psychology both play a role in figuring out what ails the brain as well as the person. This is where...
