Brodmann area 22 is one of Brodmann's cytologically defined regions of the brain. It is involved in auditory processing. ==Human== Brodmann area 22 the region of the human brain (the 22nd numbered Brodmann area). On the left side of the brain this area helps with generation and understanding of individual words. On the right side of the brain it helps to discriminate pitch and sound intensity, both of which are necessary to perceive melody and prosody. Researchers believe this part of the brain is active in processing language. This area is also known as superior temporal area 22, and it refers to a subdivision of the cytoarchitecturally defined temporal region of cerebral cortex. In the human it corresponds approximately to the lateral and caudal two thirds of the superior temporal gyrus. It is bounded rostrally by the temporopolar area 38 (H), medially by the posterior transverse temporal area 42 (H), ventrocaudally by the middle temporal area 21 and dorsocaudally by the supramarginal area 40 (H) and the angular area 39 (H) (Brodmann-1909). The posterior section of Brodmann area 22 is home to Wernicke's area (most commonly in the left hemisphere only). 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Brodmann area 22」の詳細全文を読む スポンサード リンク
