Outline of Research at the Start

複数の感覚情報、特に視覚と聴覚情報を脳内で統合することを視聴覚統合といい、視聴覚統合によって私たちは、より正確な知覚が可能となる。本研究は、視聴覚統合によってどのように知覚を創り出しているか、その神経基盤の解明を目指す。申請者は、スナネズミにおいても視聴覚統合に関与する錯覚が生じることを発見した。その錯覚をモデルとして課題遂行中のスナネズミから、知覚応答と神経応答の同時記録を行うことで、神経活動が知覚を形成するメカニズムが明らかにしていく。

Outline of Annual Research Achievements

我々は複数の感覚情報を統合し外界を知覚している。例えば、単独刺激に比べ視聴覚刺激に対する刺激の検出性能が向上する。しかしながら、どのように統合が行われ知覚が形成されるかは未だ明らかになっていない。本研究の目的は、視覚情報と聴覚情報を統合する神経メカニズムの解明である。当該年度は、検出性能を向上させる神経メカニズムを明らかにするために、行動実験中の神経活動を記録するセットアップを確立した。テトロードを1次視覚野に挿入し、単独刺激及び視聴覚刺激をそれぞれ提示した。その結果、単独刺激提示時に比べ、視聴覚刺激に対する活動が変調していた。これは、1次視覚野が聴覚刺激の影響を受けている可能性を示している。
ヒトを対象に、統合が行われる条件についても検討を行った。昨年度までの成果により、2回目に提示する聴覚刺激の音圧が1回目の音圧よりも小さくなるほどダブルフラッシュ錯覚が起きにくくなることを明らかにした。当該年度は、音を知覚した回数を回答するタスクを加え同様の実験を行ったところ、2回目の音圧が小さくなるほど音を2回と知覚できる割合が減少し、錯覚が起きる割合と相関していた。これは知覚した聴覚刺激の数に依存して視知覚が変化している可能性を示唆している。
