Outline of Final Research Achievements

The cerebrum and cerebellum communicate each other to achieve sophisticated motor control and motor learning. The cerebro-cerebeller loop also plays an important role in higher-order functions. To elucidate neural circuit mechanisms for these functions, we used two-photon imaging to observe neural activity in mice performing cognitive-motor tasks, and revealed the neural representations regarding sensation, movement, and reward. We also developed novel calcium sensors that can measure neural activity with unprecedented accuracy and a data analysis method.

Academic Significance and Societal Importance of the Research Achievements

小脳は運動に関わる脳領域として長年研究が進められてきたが、その詳細な神経回路メカニズムについては未だ不明な点が多い。さらに、最近では報酬や判断など運動とは直接関係ない情報が小脳にも伝えられていることが明らかとなって注目を集めている。本研究では、これらの情報表現がどのようなものかを認知運動課題を実行中のマウスにおいて明らかにした。素早く正確な運動や判断を実現するための脳メカニズムとその獲得原理の解明に貢献する。
