Document Summary
Aphasia is speech disturbances due to brain dysfunction. Cerebral cortex helps language comprehension and production. Visual processing carried out in occipital lobe, audio processing carried out in temporal lobe. Broca"s area and wernicke"s area are involved in speech articulation and auditory- semantic interpretations. Damage to the broca"s area produces nonfluent aphasias (difficulty articulating speech) Damage to wernicke"s area produced fluent aphasias (the person speaks easily but nonsensically) Visual functions to process printed language take place in the visual cortex in occipital lobe. Hearing speech begins in the auditory cortex in the left hemisphere of temporal lobe. Interpretive functions take place in temporal and parietal lobe. The amygdala plays a role in emotional recognition, so somebody with damage to it can"t process threatening speech. Facility for articulate speech located in left frontal lobe. Broca"s research showed brain damage to different areas produces different language difficulties. Leborgne was a patient who only responded with tan tan and gestures of his left hand.
