The Japanese Society for Behavioral Neuroendocrinology (JSBN) was established in 2006 and has been active with the aim of promoting interaction among researchers in the field of behavioral neuroendocrinology and fostering the next generation of researchers. For this symposium, which marks our 20th anniversary, we are planning an international symposium centered on the keyword "sociality" that crosses a wide range of themes, from behavioral control by sex steroids, neural circuit and molecular bases, development and its disruption mechanisms, to comparative research spanning from humans to various animal species. In addition to special lectures and multiple symposium sessions by domestic and international researchers, poster presentations by early-career researchers and students are planned, making the content interesting and accessible to researchers from diverse fields as well.

Please note that non-members are also welcome to attend this symposium without having to register as a new member. We sincerely hope many of you will join us.
