CONTROL OF SYMPATHETIC OUTFLOWS BY THE HYPOTHALAMIC PARAVENTRICULAR NUCLEUS

Clinical and Experimental Pharmacology and Physiology, 1998
SUMMARY1. The functional role of the paraventricular nucleus (PVN) has been examined by studying its connections with cardiovascular neurons in the medulla and spinal cord and its influence on activity in several sympathetic nerves.2. Chemical stimulation of neurons within the PVN can elicit pressor responses and can excite reticulo‐spinal vasomotor ...

Inhibition of reactive oxygen species in hypothalamic paraventricular nucleus attenuates the renin-angiotensin system and proinflammatory cytokines in hypertension.

Toxicology and Applied Pharmacology, 2014
AIMS To explore whether reactive oxygen species (ROS) scavenger (tempol) in the hypothalamic paraventricular nucleus (PVN) attenuates renin-angiotensin system (RAS) and proinflammatory cytokines (PICs), and decreases the blood pressure and sympathetic ...

Coexistence of neuropeptides in the hypothalamic paraventricular nucleus of the sheep

Neuropeptides, 1990
The chemical organization of the hypothalamic paraventricular nucleus (NPV) of the sheep was studied immunocytochemically by using antisera raised against oxytocin (OXY), ovine corticotropin releasing factor (CRF), somatostatin (SRIF), neurotensin (NT) and vasoactive intestinal polypeptide (VIP).

Alcohol Effects on Paraventricular Hypothalamic Nucleus Morphometry

Cells Tissues Organs, 1995
The morphometric effects of postnatal exposure to alcohol on the neurons of the paraventricular hypothalamic nucleus (PVN) have been studied in four different topographic subdivisions of the nucleus: rostral, intermediate medial, intermediate lateral and caudal.

Characterization of the Parabrachial Nucleus Input to the Hypothalamic Paraventricular Nucleus in the Rat

Journal of Neuroendocrinology, 1992
AbstractThe brainstem parabrachial nucleus (PBN) is viewed as an increasingly important site for the transfer of autonomic‐related information to more rostral structures in the forebrain including the hypothalamus. In this study, we examined electrophysiologically in vivo and anatomically the nature of PBN input to the hypothalamic paraventricular ...

Dynamism of chemoarchitecture in the hypothalamic paraventricular nucleus

Brain Research Bulletin, 1988
The hypothalamic paraventricular nucleus (PVN) has been implicated in a remarkable number of functions including control of pituitary-adrenocortical activity in response to stress, body fluid homeostasis, milk ejection reflex, prolactin secretion, thyroid hormone secretion, analgesia, food intake, gastrointestinal functions, cardiovascular functions ...

Hypothalamic Paraventricular Nucleus, Oxytocin, and Maternal Aggression in Rats

Annals of the New York Academy of Sciences, 1997
Both the lesion of the parvocellular region of the PVN (FIG. 1) and the acute reduction of OT synthesis in that nucleus (FIG. 2) increase maternal aggression in rats. Previous work showed that ibotenic acid as well as the OT antisense in the PVN reduced the level of OT in the brainstem, but not in the pituitary.

Chronic infusion of norepinephrine and clonidine into the hypothalamic paraventricular nucleus

Brain Research Bulletin, 1984
Previous experiments have shown that acute injection of NE and CLON into the PVN initiates a short-term feeding response in satiated rats. This study examined, in brain-cannulated rats, the impact of remote, chronic injections of NE, CLON, or saline on daily food intake and body weight gain. Over a period of 14 days, NE was infused into the PVN, either

Presynaptic inputs to vasopressin neurons in the hypothalamic supraoptic nucleus and paraventricular nucleus in mice

Experimental Neurology, 2021
Arginine vasopressin (AVP) neurons in the hypothalamic supraoptic nucleus (SON) and paraventricular nucleus (PVN) are involved in important physiological behaviors, such as controling osmotic stability and thermoregulation. However, the presynaptic input patterns governing AVP neurons have remained poorly understood due to their heterogeneity, as well ...

The Effects of Propofol on Hypothalamic Paraventricular Nucleus Neurons in the Rat

Anesthesia & Analgesia, 2004
The mechanism of hypotension induced by anesthetics is not completely understood. Because no electrophysiologic examination of the effects of propofol on the central nervous system has shown its involvement in the control of sympathetic and cardiovascular functions, we investigated the actions of propofol on rat hypothalamic paraventricular nucleus ...
