چکیده

Electrical stimulation in medulla oblongata has been carried out in 36 dogs with the purpose of studying the mechanism of cardiovascular and respiratory regulation. By electrocardiographic registration, changes in heart beats were examined, and disturbances of heart rate and rhythm were suggested to be due to direct vagal nucleus stimulation or due to vagal reflex by arterial pressure change. Blood pressure elevation occurred often together with bradycardia. This seemed in part due to baroceptor reflex, but in other part due to primary cardioinhibitory effect. These mechanisms were discussed.

Subjective Visual Vertical and Horizontal Abnormalities in a Patient with Lateral Medullary Syndrome-A Case Report

Introduction: Evaluation of persistent vertigo in post infarct patients is very important as the management depends on whether the cause is purely of central origin or due to associated vestibular affliction.   Case Report: A patient with left sided dorsolateral medullary syndrome and persistent vestibular symptoms was evaluated. Vestibular test battery showed abnormal smooth pursuit, bilateral...

Inotropic, chronotropic, and dromotropic effects mediated via parasympathetic ganglia in the dog heart.

Some parasympathetic ganglionic cells are located in the epicardial fat pad between the medial superior vena cava and the aortic root (SVC-Ao fat pad) of the dog. We investigated whether the ganglionic cells in the SVC-Ao fat pad control the right atrial contractile force, sinus cycle length (SCL), and atrioventricular (AV) conduction in the autonomically decentralized heart of the anesthetized...

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...
