Cardiac vagal preganglionic neurones (CVPNs) are located within the dorsal vagal nucleus
(DVN) and the nucleus ambiguus (nA). In mammals, CVPNs within the nA have small …

Brainstem 5‐hydroxytryptamine (5‐HT, serotonin)‐containing neurones modulate
cardiovascular reflex responses but the differing roles of the many 5‐HT receptors have not …

To elucidate whether prolonged stimulation of cardiopulmonary serotonergic (5-HT3)
receptors could play a role in the control of renal sympathetic nerve activity (RSNA), we …

The cardiovascular effects of 5‐hydroxytryptamine (5‐HT), consisting of bradycardia or
tachycardia, hypotension or hypertension, and vasodilatation or vasoconstriction, are …

Activity in central sympathetic pathways can be modified by stimulating central ai-
adrenoceptors. eg. with clonidine, or, more recently, by stimulating central 5 …

5‐Hydroxytryptamine (5‐HT; serotonin)‐containing neurones contribute to reflex activation
of parasympathetic outflow in a number of species, but the 5‐HT receptors mediating these …

Intra-atrial administration of phenylbiguanide has been shown to trigger, through the
stimulation of vagal afferent C-fibers, reflex bradycardia, hypotension, and …

The effects of intracisternal (ic) application of the 5-HT3 receptor antagonist granisetron
(0.016–0.16 μg kg− 1) and the agonist phenylbiguanide (0.3–3 μg kg− 1) on reflex …

Evidence is provided to support the view that central 5-HT1A and 5-HT2 receptors are the
major receptor subtypes important in cardiovascular regulation. Data are also provided to …

The effects of serotonin (5-hydroxytrypta-mine; 5-HT) on the cardiovascular system are
complex. These effects, consisting of bradycardia or tachycardia, hypotension or …
