Outline of Research at the Start

前頭葉の高次運動野や頭頂連合野の傷害によって引き起こされる典型的な臨床症例の一つに、麻痺症状はないにも関わらず、外部から動作を指示された場合に指示された内容は理解していても動作として表現できないという症状がある。すなわち動作には高次な表現(動作アイディア)と実際の運動(アクション)の表現があると考えられるが、その神経基盤は依然としてわかっていない。本研究では、機能的磁気共鳴画像法 (fMRI) による脳活動の測定と、経頭蓋磁気刺激法 (TMS) を用いた一過性の機能脱落を組み合わせることで、動作アイディアの形成に関わる神経基盤の解明に迫る。

Outline of Final Research Achievements

The dorsal premotor cortex (PMd) plays an essential role in visually guided goal-directed motor behavior. Although there are several planning processes for achieving goal-directed behavior, the separate neural processes are largely unknown. We created a novel visuo-goal task that allows us to temporally separate the elements involved in movement ideas (behavioral goal) and actions, and conducted an experiment to measure the neural activity of subjects while performing this task using functional magnetic resonance imaging (fMRI) on a 7 Tesla MRI system. The results suggest that the dorsal premotor cortex is involved in linking visual information with movement ideas and actions, in converting movement ideas to actions, and in preparing for actions.

Academic Significance and Societal Importance of the Research Achievements

本研究の結果は、ヒトの運動前野背側部が動作アイディアの形成や、動作アイディアから具体的なアクションへ変換する役割を担うことを示唆するものである。この成果は、近年問題となっている高齢ドライバーが車のアクセルとブレーキを踏み間違えてしまう事故に象徴されるような、「わかっているのにできない」現象がなぜ起こるのかを理解するための重要な手がかりになると考えられる。
