Outline of Final Research Achievements |
Claryfing the characteristics of auditory processing in autism spectrum disorder, I established an analysis method by measuring brain activity while listening to sounds using a magnetoencephalography (a device that measures brain activity). By using an analysis method called the dSPM method, it was found that brain activity could be observed with better accuracy than previously reported. In particular, this method proved to be effective in observing results suggesting that the filtering mechanism (a mechanism to sort incoming sounds according to their "importance") in the left hemisphere of the brain may be reduced in high-IQ adults with autism spectrum disorder.

Academic Significance and Societal Importance of the Research Achievements |
自閉スペクトラム症を持つ方は、聴覚の過敏性と鈍感さを同時に示すことがありますが、この原因の一つとして、左脳での音の振り分けシステムの異常があることを発見しました。特に、この異常を検出するのに望ましいデータ解析手法を検証・発見しました。 脳磁計を用いて、短時間音声を聴くだけで、聴覚過敏性などの問題を定量的に評価できるようになる可能性があります。今後、さらにデータ解析を進めます。
