| Outline of Final Research Achievements |
Androgen serves as the primary stimulator of aggression in vertebrates, including teleosts. In this study, we examined the neural mechanisms underlying the induction of aggressive behavior by androgen, using medaka as a model teleost species. Our result demonstrated that androgen secreted by the testis male-specifically induces the expression of vasotocin in the hypothalamus, that androgen is capable of activating the transcription of vasotocin directly, and that vasotocin has the ability to promote aggressive behavior.
