Research Abstract

本研究では,新しい脳波(EEG)・脳磁界(MEG)データの解析法である位相系列解析を開発した.位相系列解析は単に解析方法としても機能するが,本研究では位相系列解析を前提としたEEG/MEG の測定装置・方法も含む実験全体としてデザインした.この結果,特にここ10 年間注目を浴びている脳内の位相共振現象(事象関連同期・脱同期,長距離位相共振,位相リセット)を包括的に調べる実験方法を確立した.本実験方法を用いることによって,長距離共振を行うために領野間で位相補正が起る現象が位相リセットであり,過渡的に位相が進行するとき起る現象が事象関連同期・脱同期であるとの実験的証拠を得るに至った.
