Phineas Gage Essay Example for Free

Phineas bet EssayPerhaps one of the most well known lessons in cognitive psychology is that of Phineas eatage. A man who suffered from an soil to his prefrontal lobes thirty age before the bailiwick of Psychology even began (Moulin, 2006). However, psychologists continue to study his hotshot and the effects of his injury and its role in cognitive functions years later. Phineas poop was a foreman at a railroad who suffered damage to his prefrontal lobes as a result of an shotal explosion in the year 1848. This explosion caused an iron quantity somewhat a meter long to be launched completely through scum bags head and supposedly land about nine meters away.As a result of this accident Gage suffered severe brain damage to his prefrontal lobes, with the left over(p) side being almost completely destroyed (Moulin, 2006). There is not documentation of what Gages personality was like before the accident and few reports of the changes after the incident, numerous believed to be exaggerated. Two of the reports that do exist regarding Gage atomic number 18 written by John Martyn Harlow. Harlow was the medical student who treated Gage and followed his case (III. The Damage to Gages Skull and Brain, 2002).Following his recovery of the accident there were no reports of unembellished loss of interllectial function, yet his personality changed drastically. In fact Gage behaved so different that he while he went back to work for the railroad he never was presumptuousness his job back as foreman (II. The Sequelae of the accident, 1848-1868, 2002). In fact, when asked his friends and acquaintances said he was no longer Gage (Moulin, 2006). Gage lived about eleven years after his accident before dying in 1860 which left people in the medical field curious about him and his condition (Moulin, 2006).In fact the changes in his behavior that were described was the first epoch that it was revealed that complex functions might be located in the brain. During the time and the immediate time after Gage lived there is not much medical documentation. Therefore it was years later when the exact parts of Gages brain that were damaged due to the iron bar were determined (II. The sequelae of the accident, 1848-1868, 2002). When Harlow learned of the passing of Gage, he sought out and received permission from his family to have the trunk exhumated in December of 1867 (II. The sequelae of the accident, 1848-1868, 2002).He did so in order to study the brain and learn from the injury of the skull and the result that the damages had on Gages personality. From the study he was able to determine that Gage suffered damage to three postures the area under the zygomatic arch, the base of the skull where the iron rod had entered behind the eye, and at the top of the head where the iron rod emerged (III. The damage to Gages Skull and Brain, 2002). After studies of Gages skull where complete, psychologists have been able to take the measurements from the skul l and use modern technology to determine the approximate location of the legion.Damage was caused to both the left and right prefrontal cortices in a pattern that caused a speck in rational decision making and the processing of emotion (Damasio, 1994). Studies that have been done since the case of Gage have determined that higher cognitive functions take place in the prefrontal lobes. Some of these functions implicate working memory, mental imagery, and willed actions that are associated with consciousness (Frith Dolan, 1998). Psychologists have been able to learn from this famous case of Phineas Gage.A man who took no part in experiments and whose injuries were sustained thirty years before the start of Psychology. From this case it has been determined that cognitive functions that can become impaired by prefrontal brain damage are abilities like planning, reasoning, and problem solving. It has also been shown that frontal lobe damage can affect a persons memory in a subtle mann er. While there can be no apparent loss of intellectual function as a result of prefrontal brain lesions it is can suave be tragic to the lives of those involved (Gerhand, 1999).
