Outline of Final Research Achievements

The shared intention of actions, "How", is important for interpersonal coordination. In the present study, we used a facial expression imitation task to investigate the neural basis involved in sharing action intentions and emotions (facial expressions). Combining behavioral analysis techniques with Hyperscanning-fMRI techniques, we found that the activity of the right inferior parietal lobule is synchronised in relation to pair-specific behavioural similarities. This result suggests that the inferior parietal lobule, part of the mirror neuron system, plays an important role in the shared intention of actions.

Academic Significance and Societal Importance of the Research Achievements

ミラーニューロンシステムは自分の行為の時、また他者の行為の観察の時に活動することが知られてきたが、自他の間で同じような活動パターンを示すかについては不明であった。本研究は、模倣中に右下頭頂小葉でペア特異的な活動の類似性があることを明らかにした。この類似性は「なにをするか(What)」ではなく、Howという運動の意図が共有されたことによって生じた。Howという運動の意図共有は相手の意図理解や共感において重要であり、本研究の成果は社会性障害の神経機序の理解へ貢献することが期待される。
