Comparative neuroendocrinology of steroid receptor gene expression and regulation: Relationship to physiology and behavior.
Great diversity exists among vertebrates in reproductive behaviors and the neuroendocrine mechanisms underlying these behaviors. Comparisons of species with different hormone-brain-behavior relationships reveal three factors which may explain species differences in endocrine physiology and behavior: (a) sensitivity to sex steroid hormones, (b) hormone-dependent regulation of sex steroid hormone receptor gene expression, and (c) neuroanatomical distribution of steroid receptor gene expression, especially in nonlimbic structures.
