楽曲構造における時間イメージを反映する大脳皮質バソモーション・パターンの研究  [in Japanese] Vasomotion patterns in cerebral cortex representing "l'image-temps" for musical structures  [in Japanese]

Abstract

脳の血液生理学的計測法(NIRS)による楽曲聴取・演奏時の脳活動評価法開発を目的とした.楽曲の時間軸構造・リズムパターンと前頭葉・側頭葉の皮質血流パターンの比較を,2チャネルの無侵襲酸素モニタを用いて行った.数秒〜分の時間スケールでの脳血流ダイナミクスに関する新しい知見として,1)身体動作(演奏)をイメージする楽曲の時間構造に合致した血流パターンが左前頭に現れること,2)左の側頭葉と前頭葉の間での酸素化ヘモグロビンの逆相同期現象が,楽曲中のリズムパターン変化部位に生じやすいことを得た.

Hemo-dynamics relating to musical recognition process in human brain were investigated by utilizing two one-channel non-invasive oxygen monitors (NIRS). We compared the vasomotion patterns with a musical performance and with a performance imaging, and obtained a similarity in both patterns in case with the performance by a professional pianist. Also, the vasomotion pattern in left prefrontal region became out of phase versus the left temporal region closed to auditory cortex when a rhythm pattern distinctly changed.
