Outline of Final Research Achievements

Those who are in the field of sports including athletes and coaches often struggle to fix habits in their actions and movements. The aim of this study is to understand neurophysiological mechanisms underlying the inhibition and modification of habitual actions. Developing new behavioral tasks in rats, where they had to suppress or replace their acquired habits with new actions, we tested the effect of either ablation or activation of striatal cholinergic interneurons on these tasks. We discovered that artificial activation of the striatal cholinergic interneurons enhances animals' ability to substitute a new movement for an old habit (Aoki et al., Eur J Neurosci., 2018). This finding reveals a possibility that facilitating cholinergic activity in the striatum enables us to acquire a new action by suppressing an old habit.

Academic Significance and Societal Importance of the Research Achievements

動作の癖を他の動作に置換するという概念は新しく、かつその神経基盤として線条体コリン作動性介在ニューロンの機能を明らかにできたことは行動神経科学分野における重要な知見である。また、スポーツ科学・身体運動科学分野において、どのようにして体に染みついた動きの癖を直すのかという問いは難問である。今後、ヒトを対象とした新規トレーニングの開発といった研究に対して、本研究はどのような脳部位あるいは細胞の活性化を狙ってトレーニングを行うべきかという重要知見を与えると考えられる。
