Baroreceptor-sensitive neurons in the rat paratrigeminal nucleus
(Elsevier B.V., 2003-04-30)The paratrigeminal nucleus (Pa5) is a small collection of medullary neurons localized in the dorsal lateral spinal trigeminal tract. Electrophysiological and anatomical studies showed functional Pa5 efferent connections ...

Bradykinin microinjection in the paratrigeminal nucleus triggers neuronal discharge in the rat rostroventrolateral reticular nucleus
(Natl Research Council Canada, 2004-07-01)A small collection of neurons in the dorsal lateral medulla, the paratrigeminal nucleus (Pa5), projects directly to the rostroventrolateral reticular nucleus (RVL). Bradykinin (BK) microinjections in the Pa5 produce marked ...

Cardiovascular and baroreceptor functions of the paratrigeminal nucleus for pressor effects in non-anaesthetized rats
(Elsevier B.V., 2009-05-11)Located in the lower brainstem, the paratrigeminal nucleus (Pa5) is related to cardiorespiratory autonomic reflex functions. To characterize the structures' role in blood pressure regulation and baroreflex response, both ...

Cardiovascular responses to sciatic nerve stimulation are blocked by paratrigeminal nucleus lesion
(Elsevier B.V., 2002-06-28)The paratrigeminal nucleus (Pa5) receives primary sensory inputs from the vagus, glossopharyngeal, and trigeminal nerves and has efferent projections to the nucleus of the solitary tract (NTS), rostroventrolateral reticular ...

Discharge rate profiles of paratrigeminal nucleus neurons throughout a pressor event in non-anaesthetized rats
(Elsevier B.V., 2009-05-11)Located in the lower brainstem, the paratrigeminal nucleus (Pa5) is related to cardiorespiratory autonomic reflex functions. To characterize the structures' role in blood pressure regulation and the cardiovascular reflex ...

Effects of nandrolone and resistance training on the blood pressure, cardiac electrophysiology, and expression of atrial beta-adrenergic receptors
(Elsevier B.V., 2013-05-30)Aims: This study was performed to assess isolated and combined effects of nandrolone and resistance training on the blood pressure, cardiac electrophysiology, and expression of the beta(1)- and beta(2)-adrenergic receptors ...

Methadone Increases and Prolongs Detomidine-Induced Arterial Hypertension in Horses, but These Effects Are Not Mediated by Increased Plasma Concentrations of Arginine Vasopressin or Serum Concentrations of Catecholamines
(Elsevier Science Inc, 2016)Catecholamines and arginine vasopressin (AVP) release can affect arterial blood pressure (ABP) and hemodynamic stability in standing, sedated horses. Six mature horses were included in this prospective, randomized, crossover, ...

Neuronal connections of the paratrigeminal nucleus: a topographic analysis of neurons projecting to bulbar, pontine and thalamic nuclei related to cardiovascular, respiratory and sensory functions
(Elsevier B.V., 2001-12-10)The paratrigeminal nucleus, which receives sensory input from trigeminal, glossopharyngeal and vagus nerves, has efferent projections to bulbar. pontine and possibly to thalamic structures associated with nociception, ...

Renal sympathoinhibition induced by hypernatremia: involvement of A1 noradrenergic neurons
(Elsevier B.V., 2008-11-03)Several findings suggest that A1 noradrenergic neurons in the caudal ventrolateral medulla (CVLM) contribute to body fluid homeostasis and cardiovascular regulation. Recently we demonstrated that the renal vasodilation ...
