Outline of Research at the Start

高齢化が急速に進む日本において、記憶の減退は深刻な社会問題を引き起こしている。特にワーキングメモリ(WM)は注意と密接に連携し、会話・読書・計算など日常の様々な心的活動を支える重要な機能である。だが WM の神経的な基盤については未だに不明な点が多く、激しい議論が行われている。本研究はヒトを対象としたマクロ的な神経活動の記録法に、独自開発した inter-peak interval 解析を組み合わせ、WM を支える脳の認知的メカニズムを探る。さらには非侵襲的な脳刺激法を用いて、記憶力の人為的な操作を試みる。

Outline of Final Research Achievements

I investigated neural underpinnings of memory and attention, especially working memory (WM). Results showed a critical role of neural oscillatory signals in alpha-to-beta band (8 to 30 Hz) in a maintenance of visual WM. Specifically, I found an increase in a speed of oscillatory signal along with the load and fidelity of WM contents. I also found a close relationship between the alpha-to-beta rhythm and verbal WM.

Academic Significance and Societal Importance of the Research Achievements

従来はサルなどを対象に神経律動信号の振幅とワーキングメモリの関係を示した研究が多かった。対して、本研究はヒトを対象として律動信号の速さとワーキングメモリの関係を示した。またワーキングメモリは、会話・読書・計算など日常の様々な場面で用いられる重要な能力である。本研究はその神経基盤を明らかにすることで、将来的に考えられる様々な社会応用(記憶力の向上トレーニングやアンチエイジング療法など)への足掛かりを築いた。
