چکیده

We report the case of a 43-year-old man who underwent endovascular treatment for posterior inferior cerebellar aneurysm. Significant hemodynamic changes were observed as electric stimulation was applied during coil detachment for a PICA aneurysm. We postulate that changes in heart rate and blood pressure during coil detachment were due to the electric stimulation of the tonic vasomotor center located in the rostral ventrolateral medulla, which was very close to the PICA aneurysm.

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...

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...
