Symposium

[2AS-18]【E】Molecular neurobiology of innate social behaviors: environments talk with genes

Thu. Dec 4, 2025 9:00 AM - 11:00 AM JST
Thu. Dec 4, 2025 12:00 AM - 2:00 AM UTC
Room 18(Pacifico Yokohama Conference Center 5F, 511+512)
Organizer: Kosei Sato (National Institute of Information and Communications Technology (NICT)), Tomomi Karigo (Johns Hopkins University)
Recent quantitative analyses have revealed that innate social behaviors are profoundly shaped by external and internal environments, challenging the dichotomy between learned and instinctive behaviors. In this symposium, we explore the genetic and neural circuit mechanisms underlying these socio-environmental interactions through integrative approaches spanning molecular, cellular, and organismal levels across diverse animal species.
