| Outline of Final Research Achievements |
Nuclei exhibiting morphological sex differences are termed sexually dimorphic nuclei (SDNs). The SDNs have been identified in the brain of several animal species, although the difference and similarity in the SDNs among animal species are poorly understood. In the current study, we examined the brain of mice, musk shrews, common marmosets, and quails to compare the SDNs among the animal species. There were species differences in the SDNs among mice, musk shrews, and common marmosets. However, many similarities of the SDNs were found among them. When compared quails to mice, musk shrews, and common marmosets, striking differences were found between the avian model and the mammalian models.
