Document Summary
Our knowledge on the physiology of language comes from: aphasia a primary disturbance in the comprehension or production of speech, the deficit must be isolated the patient must appear to be aware of what is happening. 90% of ppl are left hemisphere speech dominant. Process for saying the written word psychology---the stimulus travels for processing to the visual cortex. Speech production: posterior part pf cerebral hemispheres has something to say; damage to frontal lobes, difficulty express these thoughts, actually saying something involved the frontal lobes putting memories, perceptions and so on into speech. Apraxia of speech impaired ability to program movements of tongue, lips, & throat; required to produce proper sequence of speech sounds. Left anterior superior gyrus activated by intelligible speech. Wernicke"s area region of auditory association cortex (aac) on left temporal lobe-- in the posterior superior temporal lobe, is involved with speech perception.
