Document Summary

The most powerful evidence for the theory of specialized brain areas involves aphasia (loss of speech) Broca"s aphasia difficulty producing language (speaking: damage to the left inferior gyrus (left cerebral hemisphere near front of the brain) Wernicke"s aphasia difficulty in speech comprehension (without lacking speech production: damage to the left side but closer to the back. Brain imaging studies allow for different results to be observed from different responses: language disorders resulting from brain damage an imaging studies of language tell us that functions are localized in specific brain areas. Brain lesions (destruction of specific brain structures: used to identify brain structure-function relationships involved lesions . Brain stimulation studies: electrically stimulating the brain directly. Non-human stimulation/recording: microelectrodes in different subcortical structures of rats to locate structures that drive behaviours. Human brian stimulating and imaging techniques: researchers stimulate a subjects" brain and record the localized brain activity to generate maps of the human brain at work.
