Outline of Final Research Achievements

In order to clarify the neural circuit in the brain of the repetitive stereotypy and its control mechanism in autism spectrum disorder (ASD) using magnetoencephalography (MEG), we created a task to be performed by the participant during MEG measurement and developed the experimental system. In addition, we created the task underwent during MEG measurement, and constructed an experimental system to clarify the neural circuit in the brain caused the abnormality of gaze cognition of ASD. We wrote and submitted treatises related to these achievements, and made presentations at academic conferences.

Academic Significance and Societal Importance of the Research Achievements

自閉スペクトラム症は社会性の生涯から不登校、引きこもりなどの原因ともなっており、その原因究明とよりよい治療の開発は社会的課題である。自閉スペクトラム症の反復常同性や視線認知の異常の原因を明らかにするための実験系を構築した本研究成果は、自閉スペクトラム症の原因究明につながる、今後の研究に資するものである。
