Document Summary

Equipotential: every part of the brain does the same sort of thing in the same way without specialization. Shown by seeing if brain damage to distinct parts causes particular patterns of abnormality. Aphasia: loss of the ability to speak resulting from brain damage: broca"s aphasia: a language disorder resulting from brain damage in which the primary difficulty is with producing language (speaking) rather than understanding language. Associated with damage to the left inferior frontal gyrus, part of the left cerebral hemisphere near the front of the brain. Make ablations (precise brain lesions) in non-human species. Can see if stimulating one part, what body part moves. Non-human stimulation/recording: microelectrodes placed in brain to study behaviours. Recording is used to examine the sensitivity of neurons in a particular brain region to events in the world or to the performance of different tasks. Human brain stimulation and imaging: generate maps of brain by stimulating brain and recording localized brain activity.
