Explain The Localization Of Brain Function

The Localization of Brain Functions There are so many experiments to prove the theory of the brain, localization of brain functions.The main term that is about the theory is lateralization. Lateralization can be described as that localization of brain functions on the different parts of brain. Basicly, brain has two hemisphere, left and right. According to this, left hemisphere controls right side of the body, right hemisphere controls left side of the body. Both hemisphere have also some specific parts that have different jobs and this jobs can not be done by another part. Brain localization theory is proven by experiments so far. Examining a brain that damaged, EEG (Electroencephalogram) , fMRI are the techniques that allow us to explain localization of brain functions. The aim of this essay is to explain localization, describing three experiments to provide evidence for the localization of brain functions,discussing one of the problem with this theory. One of the experiments that proves the localization was carried out by Pierre Paul Broca in 1861. Monsieur Louis Leborgne was Broca’s patient. Leborgne was not able say any word or make sentences. Leborgne could say only word, ‘tan’ . …show more content…
Brain activities were measured with EEG during a verbal producing and listening experiment to find hemispheric activation during language process in children (4 - 6 years old) with autism and they were compared with typically developing controls. A leftside lateralization in the T5 - T6 regions for the gamma band (30 - 70Hz.), and increased alpha (8 - 12Hz) activity in the F7 region was found during language producing. Increased beta activity was found during the extent tasks. Gamma activity in the F7-F8 regions was found that they were negatively correlated with language production and comprehension performance (Carpenter, 2011). This provides us an evidence for brain localization
