Document Summary

Brain as equipotential: latter theory proposed that the brain was equipotential (every bit of the brain does the same sort of thing without specialization) To figure this out is to see if people with damage to distinct parts of their brain show particular patterns of abnormality or whether the more damage a brain has sustained the more abnormal the behaviour. Yu can also use brain imaging techniques to see which parts of the brain are activated for different tasks. Aphasia and localization: aphasia the loss of the ability to speak. Broca"s aphasia - language disorder resulting from brain damage difficulty producing language rather than understanding language. Damage in the left hemisphere towards the front part of the brain. Wernicke"s aphasia deficit in speech comprehension without a loss of in speech production. Damage in the left hemisphere towards the back part of the brain. Lesions - destruction of specific brain structures.
