Document Summary

Psyc week 6- neuroscience 2, neuropsychology and cognitive neuroscience. Damage to the brain, always has an impact. Measurement, brain scans; all areas have functions, can"t find single inactive neurons. Costs, 20% of all energy that we take in goes to our brain, brain weighs 2% of the body"s total weight, risk during child birth due to brain size. Aphasia: the loss of the ability to speak. Broca"s aphasia: a language disorder resulting from brain damage in which the primary difficulty is with processing language (speaking) rather then understanding it. Wernicke"s aphasia: a deficit in speech comprehension without a loss of speech production, damage to the left side of the brain. Left inferior frontal gyrus is particularly involved in generating verbs. Language disorders resulting from brain damage and imaging studies of language and other functions tell us that functions are localized in specific brain areas. These studies produce reliable, valid, and objective results. Brain lesions: destruction of a specific brain structure.
