Document Summary
One side is more "dominant" (i. e. left hemisphere more dominant if you right handed) Humans are 90% right handed, but animals 50/50. Language is most lateralised out of all behavioral functions. Left hemisphere controls speech & better @ comprehension. Stoke in left brain --> aphasia (problem with production & comprehension of speech) Left hemisphere is more active when person speak/listen to speech (brain imaging) People understand word faster if listened from right ear. Broca"s area (lower posterior region of left frontal lobe) Damage = difficulty speaking, but can understand speech, sing & draw. Patients are aware of their deficit, often frustrated. Wernicke"s area (posterior region of left temporal lobe) Damage = problem with speech comprehension, produce fluent but meaningless speech, cannot read. A surgery done to epilepsy patients (cut corpus callosum callosotomy) So electrical storm (convulsions) in brain does not spread & amplify = So electrical storm (convulsions) in brain does not spread & amplify = shorter.
