Investigating the Role of Hypothalamic Paraventricular Nucleus in Nociception of the Rat

International Journal of Neuroscience, 2008
The role of hypothalamic paraventricular nucleus (PVN) in nociception was investigated in the rat. Electrical stimulation of the PVN increased pain threshold, and microinjection of L-glutamate sodium into the PVN also elevated pain threshold in a dose-dependent manner, whereas cauterization of the PVN decreased pain threshold.

Organization of the hamster paraventricular hypothalamic nucleus

Journal of Comparative Neurology, 1993
AbstractThe hamster periventricular hypothalamic area has been the focus of functional research concerning photoperiodic time measurement. These studies have relied upon the extensive analysis of rat paraventricular nucleus because there has been a general absence of anatomical description in the hamster.

Organization of the human paraventricular hypothalamic nucleus

The Journal of Comparative Neurology, 2000
The cyto- and chemoarchitecture of the human paraventricular hypothalamic nucleus (Pa) was studied with the aid of three-dimensional computer reconstruction. The adult human Pa is a vertically elongated structure that abuts the wall of the third ventricle (3V) medially and is indented dorsolaterally by the descending fornix.

Glucosensing in parvocellular neurons of the rat hypothalamic paraventricular nucleus

European Journal of Neuroscience, 2011
AbstractSpecialized hypothalamic neurons responding to rising extracellular glucose via increases or decreases in their electrical activity [glucose‐excited (GE) and glucose‐inhibited (GI) cells, respectively] have been reported in the hypothalamic arcuate, ventromedial and lateral nuclei.

ROLE OF THE HYPOTHALAMIC PARAVENTRICULAR NUCLEUS IN CARDIOVASCULAR REGULATION

Clinical and Experimental Pharmacology and Physiology, 1996
SUMMARY1. The paraventricular hypothalamic nucleus (PVH) is a complex structure with both neuroendocrine and autonomic functions. It is a major source of vasopressin and the primary source of corticotropin‐releasing factor. In addition, parvicellular PVH neurons have reciprocal connections with brain‐stem autonomic centres and directly innervate ...

CONTROL OF SYMPATHETIC OUTFLOWS BY THE HYPOTHALAMIC PARAVENTRICULAR NUCLEUS

Clinical and Experimental Pharmacology and Physiology, 1998
SUMMARY 1. 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.

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 ...

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 ...
