Outline of Research at the Start

近年,脳を模した深層神経回路が画像認識などにおいて人と同等かそれを凌駕する性能を実現している.しかし,現在の深層神経回路はそのエネルギー効率や学習効率に大きな問題があり,生体脳における深層神経回路がこれらの性能を実現するメカニズムを明らかにすることが次世代の課題だと言える.本研究では,大規模公開データおよびマウス等でのシナプスレベル活動計測を通して,生体脳の異なるレイヤーでの情報の伝達および単一ユニット(=神経細胞)による入力の統合のメカニズムを解析する.これによりマルチセルラ系の学習則の生物学的基盤を明らかにする.

Outline of Final Research Achievements

The goal of understanding the characteristics of information processing in biological brains has led to multifaceted research at the synaptic, cellular, and cerebral network levels. Particularly at the synaptic and cellular levels, insights were gained into the mechanisms of visual information transmission and neural circuit development in different brain regions during sensory information processing in the cerebral cortex's visual areas. Furthermore, at the synaptic level, a new analysis method for synaptic development in cultured cell systems was proposed. Additionally, research primarily at the cerebral network level focused on the inherent spontaneous activity of biological brains, combining human brain big data with model animal brain analysis, and developing novel analysis methods using deep learning and machine learning.

Academic Significance and Societal Importance of the Research Achievements

この研究は、生体脳の情報処理機構を深く理解するための基礎を築くことに貢献するものである。学術的には、シナプスや細胞の動作原理に関する新しい知見を提供し、大脳ネットワークを通じた情報の流れの解明に貢献する。社会的には、神経変性疾患の早期発見や治療法の開発、教育や人工知能技術の向上に役立つ可能性があり、幅広い分野に影響を与えることが期待される。
