Medullary Norepinephrine Projections Release Norepinephrine into the Contralateral Bed Nucleus of the Stria Terminalis
Central norepinephrine signaling influences a wide range of behavioral and physiological processes, and the ventral bed nucleus of the stria terminalis (vBNST) receives some of the densest norepinephrine innervation in the brain. Previous work describes norepinephrine neurons as projecting primarily unilaterally; however, recent evidence for cross-hemispheric catecholamine signaling challenges ...
متن کاملGlutaminergic 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...
متن کاملIn vivo voltammetry monitoring of electrically evoked extracellular norepinephrine in subregions of the bed nucleus of the stria terminalis.
Norepinephrine (NE) is an easily oxidized neurotransmitter that is found throughout the brain. Considerable evidence suggests that it plays an important role in neurocircuitry related to fear and anxiety responses. In certain subregions of the bed nucleus of the stria terminalis (BNST), NE is found in large amounts. In this work we probed differences in electrically evoked release of NE and its...
متن کاملVentral subicular interaction with the hypothalamic paraventricular nucleus: evidence for a relay in the bed nucleus of the stria terminalis.
The axonal projections of the ventral subiculum to the bed nucleus of the stria terminalis (BST) were examined in the rat with the anterograde neuronal tracer Phaseolus vulgaris-leucoagglutinin (PHA-L). Axons originating in the ventral subiculum coursed to the BST through either the fimbria-fornix, or a pathway involving the stria terminalis via the amygdala. Ventral subicular axons gave rise t...
متن کاملGABAergic receptors in rostral ventrolateral medulla mediates the cardiovascular responses to activation of bed nucleus of the stria terminalis in the female rat
The bed nucleus of the stria terminalis (BST) is 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 GABA-A antagonist receptors, bicuculline methiodide (BMI), in the rostral ven...
