Outline of Final Research Achievements |
Even subtle changes in environmental factors can exert behavioral effects on creatures, altering interspecific interactions and eventually affecting the ecosystem. However, how animals associated with complex behaviors regulated by neural processes adapt to the changes in the environment is largely unknown. The freshwater planarian Dugesia japonica displays distinct behavioral traits mediated by sensitive perception of environmental cues. Planarians are thus beneficial organisms for examining interactions between environmental changes and specific behaviors of animals. Here we found that the signaling from the peripheral pharynx nervous system to the brain and the sensitivity of the chemosensory neurons directly modulated by the environmental chemical factor critically impact individual feeding behavior related with the growth and survival in planarian. These results suggest that the peripheral nervous system orchestrates planarian behavior at the individual animal level.

Academic Significance and Societal Importance of the Research Achievements |
動物行動における環境適応性の複雑な作動原理については大部分が不明である。本研究では、環境変化に伴ってプラナリアが出力行動を適応的に選択する現象に着目し、その機構を非常に単純な原理として理解しようとする点が独創的であり学術的に意義深い。また、水生生物であるプラナリアの行動様式の機構に関する研究は、SDGsの「9.産業と技術革新の基盤をつくろう」および「14.海の豊かさを守ろう」に貢献する。
