| Outline of Final Research Achievements |
Teleost fish exhibit sexual dimorphisms in a range of traits that influence their productivity and economic value, including aggression, mating behavior, growth, sexual maturation, and stress response. Many of these sexual dimorphisms in traits presumably stem from those within their brains; however, it is still unclear what sexual dimorphisms exist within their brains, how these dimorphisms are established, and what traits these dimorphisms are relevant to. In this study, we focused on three sexual dimorphisms we have recently found in the medaka brain, and investigated the mechanisms of establishment and physiological significance of these dimorphisms.
