Study on the Bed Nucleus of Stria Terminalis in Relation to Gonadotropin Control

Study on the bed nucleus of stria terminalis in relation to gonadotropin control.

Role of the bed nucleus of stria terminalis (BST) in the control of gonadotropin release in the female rat was studied. Electrical stimulation of the BST on the day of diestrus II increased the serum concentration of FSH, but not of LH. The stimulation on the day of estrus increased serum concentration of LH as well as on the day of proestrus. In the ovariectomized and estrogen-treated rat, the...

Effect of GABAA Receptors in the Rostral Ventrolateral Medulla on Cardiovascular Response to the Activation of the Bed Nucleus of the Stria Terminalis in Female Ovariectomized Rats

Background: The areas of the bed nucleus of the stria terminalis (BST) with a high density of estrogen receptors are involved in cardiovascular regulation and send axonal projections to the rostroventrolateral medulla (RVLM). We aimed to find the contribution of the RVLM to cardiovascular responses elicited by glutamate microinjection into the BST. Methods: Experiments were done in α-ch...

Epigenetic 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...

The role of the bed nucleus of the stria terminalis in learning to fear.

Glutaminergic receptor in the rostroal ventrolateral medulla mediate the cardiovascular responses to activation of the bed nucleus of the stria terminalis in female ovariectomized rat

Introduction: Experiments were done to investigate the cardiovascular response to glutamate (Glu) injection in the bed nucleus of stria terminalis (BST) in urethane anesthetized ovariectomized (OVX) or OVX estrogen  treated (OVX+E)  female Wistar rats. In this study also the effect of glutaminergic system of the rostral ventrolateral medulla (RVLM) on Glu stimulation of cardiovascular...
