Phineas Gage Case Study

Another study from the 19th century which further revealed important and new information about the function of specific areas of the brain was by paul broca (1824-80) broca wanted to investigate tans unusually language abilitycapability by studying his brain. He selected 11 patients who had severed corpus callosums, where the corpus callosums were severed in epilepsy sufferers to prevent seizures crossing from one side of the brain to another. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices.

If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. Previous findings on brain structures involved in violence are supported and new findings revealed. This could be due to the fact that the left hand side of the body is controlled by the right hemisphere, which is also the creative hemisphere.

Laterization of function include the assertion that the right half of the brain is dominant for visuo-spatial ability (demonstrated in tasks like reading maps or recognizing faces), as well as musical abilities and understanding intonation in speech. Matched with 41 participants (controls) was selected based on sex, age and matched to a ngri participant  each participant was injected with a glucose tracer (bonds to substances like glucose) (for pet scans)  as the brain uses substances like glucose (as energy) the areas of the brain that are most active absorb it the glucose is broken down but the radioactive materials remain and it emits positively charged particles called positrons, which are picked up by the scan this information can be read by the computer, producing coloured images on the level of activity throughout the brains they had to perform tasks requiring them to detect target signals for 32 minutes  compared level of activity (glucose metabolism) in the right and left hemispheres of the brains and the control participants  less activity in the parietal and pre-frontal cortex of the brain of those participants charged with murder  more activity in the occipital areas and no difference in their temporal areas  lack of activity in the amygdala - indicating that violence was due to unusual emotional responses (e. It is generally accepted that there are two hemispheres within the brain which each control separate functions.

The aim of the experiment was to discover (using pet scans) if murderers who pleaded not guilty by reason of insanity (ngri) to show evidence of brain abnormalities (by observing the cortical and subcortical parts of the brain) was to compare the functioning of various brain structures between ngris and normal subjects using pet scanning technologies the independent variable in this study was whether the participant was a ngri or not. The left half of the brain seems to be more positive than the right and is dominant for language and logical or mathematical abilities. Furthermore, more research needs to be undertaken regarding people who do not have a severed corpus callosum, so that it can be distinguished as to whether sperrys results can be applied to the general population.

The findings do not mean violence is caused by biology alone (other social, psychological and situational factors are involved). Through studies like wernicke and brocas, it became clear that specific parts of the brain were responsible for specific human activities and behaviour. It does not mean pet scans can diagnose murderers and do not say whether the brain abnormalities are a cause or effect of behaviour.

Specifically detailing what part of the brain was affected, how the researcher found out, and what the effect on behaviour, cognition or emotion was. It does not demonstrate that the murderers are not responsible for their actions. In order to write a good response, you need to describe the study and clearly indicate how it shows that brain functions are localized. For example wernicke you cant really explain the study as he never really conducted an official study, but if you choose broca then try and explain wernickes study with it. .

The findings do not mean violence is caused by biology alone (other social, psychological and situational factors are involved). Differences were found in the amygdala and corpus callosum of the ngris, amongst various structures, suggesting differences in their experience of emotion of fear and their inability to contemplate consequences of their actions  the use of this new technology enables psychologists to see the functioning structures of the brain whilst performing specific tasks  this hence allowed raine to compare the functions of various brain regions, effectively showing changes in these areas in ngri subjects and how they subsequently affect subjects functioning  an influential study, which helped neuroscientists to understand the way brain functions appear to be not only localized in specific regions, but also lateralized that is, the left and right hemispheres seem to be more or less responsible for certain activities was from the work of roger sperry (1968). Therefore it is said that many functions of the brain are strictly localised. It does not mean pet scans can diagnose murderers and do not say whether the brain abnormalities are a cause or effect of behaviour. Through this study, new understanding and research had arised of localised functions? Of different parts of the brain, as a result of this finding from early research into the brain by scientists such as broca. He selected 11 patients who had severed corpus callosums, where the corpus callosums were severed in epilepsy sufferers to prevent seizures crossing from one side of the brain to another. The tasks included being shown an image on the left or right hand side of their body, where they were asked to identify it or asked to drawn pictures with their left or right hands based off an example. To test the effects of a severed corpus callosum, and therefore prove that the two hemispheres have separate functions. The dependent variable was the pet scan results between the controls and the ngris.

Previous findings on brain structures involved in violence are supported and new findings revealed. From harlows study of phineas gage, it can be concluded that gages frontal lobes were indeed damaged in the left pre-frontal region, which accounted for his disinhibited behaviour. Harlow described him as having little restraint, using extremely rude language, and making grand plans for the future, which would be instantly replaced with others. Broca concluded that the area named after him (brocas area) is responsible for an impairment of language in a person.

    The left half of the brain seems to be more positive than the right and is dominant for language and logical or mathematical abilities. Although, sperry only had 11 participants, he found significant information into the insight of localization of brain function as well as laterization, which is the theory that the two hemispheres have separate functions. His research allowed other research to form and take place to gain more insight into how the different parts of the brain functions.

Wernicke worked in a similar fashion to broca, by noting behaviour and conducting post-mortem autopsies to locate brain damage after patients had died, particularly in stroke victims. Individuals with this type of aphasia might have problems understanding the speech of others or might substitute wrong words into planned phrases.

Therefore, damage to relevant areas of the brain can cause drastic loss of that function and even more, depending on the individual. The effects of damage to this part of the brain can most easily be observed in the speech of stroke victims, many of whom are temporarily or permanently unable to produce language, a condition known as brocas aphasia.
