Abstract
Sex differences in adult neuroendocrine and behavioral responses largely depend on differences in the organization of the brain. Many of these are brought about by the exposure of undifferentiated brain to perinatal gonadal hormones, especially aromatizable androgen or estrogen (Goy and McEwen 1980; MacLusky and Naftolin 1981; Arai et al. 1983). Recent studies indicate that sex steroid hormones modulate and promote neuronal maturation and neurite growth in certain brain regions (Toran-Allerand 1984). Synaptogenesis can also be facilitated by estrogenic action in the hypothalamic arcuate nucleus (ARCN) and medial amygdaloid nucleus (MAN) during early postnatal development (Arai 1981). These organizational effects of gonadal steroids appear to be regionally specific and correlated with the presence and topographic localization of the sex steroid receptor-containing neurons (Goy and McEwen 1980).
