Outline of Research at the Start

自閉スペクトラム症は人口の数パーセントに見られる発達障がいである。その症状として社会疎通性の障害が注目されがちだが、もう一つの中核症状である活動と興味の範囲の著しい限局性も、たとえ知能が平均もしくは平均以上であっても、当事者の社会生活に大きな影響を与えている。本研究では、「この自閉症に見られる認知の硬直性が神経活動の過度の安定性にあるのではないか」という仮説を独自の統計解析手法および心理実験パラダイムを用いて検証する。さらに新たに開発する動的脳刺激法によって、その神経-行動相関の因果性を実証し、将来的な非侵襲的治療のヒントを探る。

Outline of Final Research Achievements

In this project, we aimed to launch a system in which we could track brain state dynamics almost simultaneously and also control it with non-invasive neural stimulation methods, such as TMS. To this end, we first extended “Energy landscape analysis” and built such brain-state-driven neural stimulation (BDNS) system. Next, using the BDNS system, we found that, some brain-behaviour causality cannot be detected without monitoring brain state dynamics and stimulating a specific brain region at the right timing in terms of such brain state dynamics. Finally, we showed that a longitudinal BDNS-based neural stimulation over autistic individuals could mitigate their cognitive and sensitive rigidity. Furthermore, we found that such BDNS could make the atypical social interactions seen in autistic individuals closer to those seen in typically developing ones.

Academic Significance and Societal Importance of the Research Achievements

学術的意義は、1. 方法論的発展として、エネルギー地形解析をより多くの脳領域を対象にも行えるように拡張したという点と、2. 概念的進歩としては、brain-behaviour causalityが脳活動状態依存に変化することを明らかにした点とがある。社会的意義は、この方法を用いることで、高機能自閉スペクトラム症の認知の硬直性や感覚の硬直性、社会疎通性の非定型性が緩和される傾向となった、という点にあると思われる。
