ブロードマン領野41,42野は,上側頭回に位置し,聴覚皮質としてみなされている。聴覚機能の基本は周波数分析だが,ヒト聴覚皮質における周波数地図については,最近,マカクザル聴覚皮質の入出力に関する知見と照合するまで一定しなかった。聴覚皮質は,条件づけ学習,人工内耳手術後などで可塑性を示し,音声知覚や音楽鑑賞や統合失調症における幻聴などは,視床や前頭葉や辺縁系などの他領域との連関によって説明できる。
Abstract
Brodmann areas 41 and 42 are located in the superior temporal gyrus and regarded as auditory cortices. The fundamental function in audition is frequency analysis; however, the findings on tonotopy maps of the human auditory cortex were not unified until recently when they were compared to the findings on inputs and outputs of the monkey auditory cortex. The auditory cortex shows plasticity after conditioned learning and surgery of cochlear implant. It is also involved in speech perception, music appreciation, and auditory hallucination in schizophrenia through interactions with other brain areas, such as the thalamus, frontal cortex, and limbic systems.
