The effects of lesions of the bed nucleus of the stria terminalis on sodium appetite.

چکیده
Lesions of the bed nucleus of the stria terminalis result in decrements in sodium ingestion. Specifically, sodium ingestion that is aroused by mineralocorticoids, in addition to sodium depletion, was reduced in rats with large lesions of the bed nucleus of the stria terminalis. Need-free salt ingestion was also reduced. These results suggest that the bed nucleus of the stria terminalis may be involved in the regulation of sodium appetite.

Glutaminergic receptors in rostral ventrolateral medulla mediate the cardiovascular responses to activation of bed nucleus of the stria terminalis in female rats
The bed nucleus of the stria terminalis (BST) has been known to contain estrogen (E)-concentrating neurons. In addition, injections of E into BST have been reported to potentiate the sympathoinhibitory arterial pressure (AP) and heart rate (HR) responses elicited by glutamate (Glu) stimulation. In this study, the effect of glutamate antagonist receptors in the rostral ventrolateral medulla (RVL...

متن کاملThe role of muscarnic cholinergic receptor of the bed nucleus of stria terminalis on cardiovascular response and baroreflex modulation in rat.
Introduction: The bed nucleus of the stria terminalis (BST) is a limbic structure which is involved in cardiovascular regulation and baroreflex modulation. The presence of cholinergic synaptic terminalis with high level of muscarinic receptors in the BST has been demonstrated. This study was performed to find the role of the cholinergic muscarinic receptor in cardiovascular response and baro...

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...

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...
