Cerebral Cortex and Phineas Gage

rational Cortex and Phineas impale Debbie Mintz PSY 360 July 25, 2011 Phineas security write up Phineas Gage was a domain who was a leader at his job and was a very like competent person. His family and friends agree that he would helpful to any ane, he was happy, and easy-going person. Then he true creative thinker hurt to his intellectual cortex, which is ones cognitive operate ons atomic number 18 in spite of appearance their lobes located in the humor. human beings have four kinds of lobes located indoors the cerebral cortex that do diametrical drop deads.Human Brain The human originator is covered with interweave cognise as the cerebral cortex, which large furrows (fissures) and small furrows (sulci), and on that point are ridges between the fissures and sulci known as gyri. Under the cerebral cortex tissue are four lobes, each lobe has a role in a creation cognitive manipulations. Phineas Gage was a man who received brain deterioration, and one voliti on be able to see how it modify his cognitive functions. Four Lobes for Cognitive Functions essentially the cerebral cortex is divided into four lobes beca apply during development of our brain the pressure divides the neighborhood into four plains and the development of these lobes do several(predicate) functions within our brain. The four lobes are known as head-on lobe, lay lobe, parietal lobe and the occipital lobe (Pinel, 2009). Ones occipital lobe is what gives him or her visual input and helps overhaul their manner, the occipital cortex with large areas of an coterminous cortex perform this cognitive function (Pinel, 2009, p. 69).In, the parietal lobe it has twain large utilitarian areas, the post central gyrus function, which it analyzes sensations one can feel from his or her body, much(prenominal) as touch. In the posterior naval division of the parietal lobes has the role of perceiving the location of twain objects and our own bodies and in directing our h elp (Pinel, 2009, p. 69). The cortex of ones temporal lobes, which has three functional areas. For ones language and hearing there is the prime(prenominal) temporal gyrus, the inferior temporal cortex identifies ones complex visual patterns, next is the average ortian of the temporal cortex its cognitive function is for memory. The last of the four lobes is the frontlet lobe, and it has two distinct functioning areas. The first area is the pre-central gyrus along with the adjacent frontal cortex have a push function, and the frontal cortex anterior to repel cortex performs complex cognitive functions (Pinel, 2009, p. 69), such as assessing the outcomes of possible patterns of behavior, preparation to reply with sequences, and assessing the signifince of the behavior of others (Pinel, 2009).Summary of what each lobe does occipital lobe for vision processing Parietal lobe for movement, information to stimuli, recognition, orientation. Temporal lobe for perception and recognitio n of auditive stimuli, speech, and memory. Frontal is for reasoning, parts of speech, movement, planning, problem-solving, and emotions (Brain Structures and their Functions, 2005) Phineas Gage (1823-1860)Phineas Gage is a good example to use when explaining what happens to a person who receives brain damage and how the damage can affect ones cognitive functions. At the age of 25 a young mans keep permuted completely, Phineas Gage was a hard worker as well as the a supervisor for the crew he worked with, his or her job was to blast huge rocks to knead the land ready for the railroad underwrite in 1848. His job consist of victimization a monkey iron on the boulders that had gun power or explode in them to explode, accidents do happen, and Phineas Gage received a tampering iron change integrity into his face.It was remarkable that he was alive as well as being able to walk three miles to find medical checkup help. The doctor cleaned him up with amazement that he lived with t his damage to his brain. From the doctors report the tampering iron made entry in the cranium and passed with the anterior left(a) lobe, and made its exit in the medial line, along his sinus fracturing his frontal and parietal bones widely, substantial parts of the brain broken up and his left optic globe was protruding out the socket, within a half of a diam (Mo, 2006).After this terrible accident gibe to (Mo, 2006), Phineas Gage retained full self-denial of his reason, but Gages wife, family, and friends began to see dramatic changes casualty to him and his constitution. Even the company he worked for tried to rehire him, but they could not because his behavior changed, he was mouthy, unpredictable, disrespectful, and grossest profanities. These was not Phineas Gages behavior forward the tampering iron went through his brain and rearrange his cognitive function from his anterior left lobe (Mo, 2006).Which is located in the frontal lobe, and it is for reasoning, parts of speech, movement, planning, problem-solving, and emotions (Brain Structures and their Functions, 2005). This was not the Phenias Gage they knew in fact anyone that knew Gage before states there is a drastic change to his mind. As a result of Phineas damage from his frontal cortex there was a complete loss of social inhibitions, and unbefitting behavior (Mo, 2006). To this day the role of the frontal cortex is involved in personality changes and social cognition (Mo, 2006, p. ) Phenias Gage lived a several(predicate) life as a stable person, at a bit where he was not known, presumably someplace in Chile and live 13 more years. This shows that when ones brain has damage that they can live through it, but as a different person. Ones cognitive functions can become neutered by brain damage within their lobes in their brain. Phineas Gage he seemed to rescind from a good natured person to a knotty natured person, does that mean a bad natured person can become neutered to a good nat ured person?
