Document Summary
The anatomy of language: sylvian (lateral) fissure: a large fissure (sulcus) on the lateral surface of the cerebral cortex 1st descr"d by the anatomist franciscus sylvius. The sylvian fissure separated the frontal cortex from the temporal lobe below: wernicke"s area: area of human l posterior superior temporal gyrus: identified by carl. Wernicke in the 19th century: broca"s area: an area located in the l hemisphere of the frontal cortex that is imp to language production. Anomia is the inability to find the words to label things in the world. A l-hemisphere network involving the frontal, parietal, and temporal lobes is especially critical for language production and comprehension. The r-hemisphere does have roles in language, especially in processing the prosody of language. Apraxia results from lesions of the cerebral cortex, usually in the l hemisphere: broca"s aphasia: the oldest and perhaps best-studied form of aphasia, characterized by speech difficulties in the absence of severe comprehension problems.
