SEXUAL-DIFFERENTIATION OF THE HUMAN HYPOTHALAMUS IN RELATION TO GENDER AND SEXUAL ORIENTATION

Recently, sex differences in the structures of the human hypothalamus and adjacent brain structures have been observed that seem to be relat ed to gender, to gender problems such as transsexuality, and to sexual orientation, that is, heterosexuality and homosexuality. Although the se observations have yet to be confirmed, and their exact functional i mplications are far from clear, they open up a whole new field of phys iological structural-functional relationships in human brain research that has so far focused mainly on such relationships in pathology.
