Sexual differentiation of the bed nucleus of the stria terminalis in humans may extend into adulthood.
Gonadal steroids have remarkable developmental effects on sex-dependent brain organization and behavior in animals. Presumably, fetal or neonatal gonadal steroids are also responsible for sexual differentiation of the human brain. A limbic structure of special interest in this regard is the sexually dimorphic central subdivision of the bed nucleus of the stria terminalis (BSTc), because its siz...
متن کاملApoptosis during sexual differentiation of the bed nucleus of the stria terminalis in the rat brain.
The bed nucleus of the stria terminalis (BST) in the rat forebrain differs between males and females. To test whether apoptosis may contribute to the development of sex differences in the BST, the incidence of apoptosis was determined in sham-treated males and sham-treated females sacrificed on postnatal days (PN) 2, 4, 6, 8, 10, and 12 (PN 1 being day of birth). More apoptotic nuclei were foun...
متن کاملEpigenetic control of sexual differentiation of the bed nucleus of the stria terminalis.
The principal nucleus of the bed nucleus of the stria terminalis (BNSTp) is larger in volume and contains more cells in male than female mice. These sex differences depend on testosterone and arise from a higher rate of cell death during early postnatal life in females. There is a delay of several days between the testosterone surge at birth and sexually dimorphic cell death in the BNSTp, sugge...
متن کاملSexual dimorphism of the bed nucleus of the stria terminalis and the amygdala.
The present review summarizes the up-to-date knowledge on the sexual dimorphism of the CNS with special regard to the sexual differentiation of the bed nucleus of the stria terminalis (BST) and the amygdala in rat. The authors provide new evidence for the sexual dimorphism and differentiation of GABAergic, leucine-enkephalin-containing and parvalbumin-immunoreactive neurons in the BST and the a...
