Gastric afferents to the paraventricular nucleus in the rat

Experimental Brain Research, 1991
Extracellular recordings were made from vasopressin (AVP) and oxytocin (OXT)-secreting cells in the paraventricular nucleus (PVN) of the hypothalamus in rats anesthetized with urethane-chloralose to determine the effects of electrical stimulation of vagal gastric nerves and gastric distension on their activity.

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.

Heterosynaptic modulation in the paraventricular nucleus of the hypothalamus

Neuropharmacology, 2019
The stress response-originally described by Hans Selye as "the nonspecific response of the body to any demand made upon it"-is chiefly mediated by the hypothalamic-pituitary-adrenal (HPA) axis and is activated by diverse sensory stimuli that inform threats to homeostasis.

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.

Organization of the neuroendocrine and autonomic hypothalamic paraventricular nucleus

2021
A major function of the nervous system is to maintain a relatively constant internal environment. The distinction between our external environment (i.e., the environment that we live in and that is subject to major changes, such as temperature, humidity, and food availability) and our internal environment (i.e., the environment formed by the fluids ...

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 ...

Electrophysiology of limbic forebrain and paraventricular nucleus connections

Brain Research Bulletin, 1986
The connections of forebrain structures with the hypothalamic paraventricular nucleus (PVN) were examined electrophysiologically in anaesthetized male rats. Single unit recordings from 336 neurons were made within the cingulate cortex (CC, n = 78), lateral septum (LS, 114), bed nucleus of the stria terminalis (BST, 27).

Efferent projections of the paraventricular thalamic nucleus in the rat

Journal of Comparative Neurology, 1995
AbstractThe paraventricular nucleus of the thalamus (PVT) receives input from all major components of the circadian timing system, including the suprachiasmatic nucleus (SCN), the intergeniculate leaflet and the retina. For a better understanding of the role of this nucleus in circadian timing, we examined the distribution of its efferent projections ...

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 ...

Relation of the Paraventricular Nucleus to the Pituitary Gland

Nature, 1954
IT is well known that the supra-optic nucleus innervates the posterior pituitary gland and that a total, bilateral destruction of this nucleus or a complete section of the supra-optieo-hypophysial tract results in diabetes insipidus1.
