Document Summary
Anatomy of the language areas of the brain. Inferior frontal gyrus, between the inferior precentral sulcus and the ascending ramus of sylvian fissure. Primary motor cortex: pars triangularis: area 45, pars orbitalis: 47/12, area 4, m1, area 6, divides the parietal lobe into the inferior parietal lobule and the superior parietal lobule. In front of the primary motor cortex is the premotor cortex. 2 subdivision of the inferior parietal lobules: Area 3, which is virtually hidden within the sulcus. The temporal lobe: starts approximately from the end of the sylvian fissure, has a very well-defined superior temporal gyrus, processes auditory information in heschl"s gyrus. Primary auditory cortex: located at the end of the sylvian fissure on heschl"s gyrus, a1, brodmann"s area 41, 42, and part of 22. Very severe damage to the inferior posterior frontal lobe causes broca"s aphasia. Broca"s aphasia is characterized by: difficulty producing language, difficulty in articulating.
