Outline of Final Research Achievements

Neural mechanisms underlying active acquisition of sensory information during social behavior have largely remained elusive due to the lack of technology that simultaneously monitors the neural activity and movement of freely behaving animals. In this study, we developed a system that non-invasively tracks the activity of specific type of neurons and movement of freely behaving fruit fly Drosophila by combining a bioluminescence probe, photomultiplier tubes, and thermography. Using this system, we uncovered a novel strategy and a neural mechanism that animals employ to communicate via pheromone signals.

Academic Significance and Societal Importance of the Research Achievements

今回開発した発光バイオセンサーを用いたシステムは、自然環境により近い状況で動物を自由に行動させ、特定の神経細胞の活動を可視化できる利点がある。このようなアプローチにより、動物がどのようにして情報交換をするのかといったコミュニケーションの戦略や、どのようにして複数の同種を見分けるのかという個体認識のメカニズムの理解につながると期待できる。また、近年発展しているゲノム編集の技術と本システムを組み合わせることで、ハエに限らずさまざまな動物において広く社会的行動の神経基盤を解明できる可能性がひらけた。
