Stimulation of the hypothalamic paraventricular nucleus causes systemic venoconstriction
Brain Research, 1993Venous capacitance plays an important role in cardiovascular homeostasis. The anatomical loci within the central nervous system involved in modulating venous function remain to be elucidated. Stimulation of the hypothalamic paraventricular nucleus is known to increase sympathoadrenal outflow and arterial blood pressure. The present study was undertaken

Feeding inhibition by urocortin in the rat hypothalamic paraventricular nucleus
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2001Ventricular administration of urocortin (UCN) inhibits feeding, but specific site(s) of UCN action are unknown. In the current studies we examined the effect of UCN in the hypothalamic paraventricular nucleus (PVN) on feeding. We tested UCN administered into the PVN in several paradigms: deprivation-induced, nocturnal, and neuropeptide Y (NPY)-induced

Leptin depolarizes rat hypothalamic paraventricular nucleus neurons
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1998Leptin, the protein product of the ob/ obgene, is thought to have a central site of action, presumably within the hypothalamus, through which it regulates feeding behavior. The paraventricular nucleus (PVN) is one structure that has been implicated in regulating feeding behavior.

Evidence for Hypothalamic Paraventricular Nucleus as an Integrative Center of Neuroimmunomodulation
Neuroimmunomodulation, 1998It has been well documented that the medial parvocellular subnucleus of the hypothalamic paraventricular nucleus (PVN) participates in immune regulation by releasing corticotrophin-releasing hormone (CRH), which triggers the hypothalamus-pituitary-adrenal axis, leading to immunosuppression.

A second hypothalamic nucleus receiving retinal input in man: the paraventricular nucleus
Brain Research, 1985A retinofugal projection to the suprachiasmatic nucleus of the hypothalamus has been described in man by means of a newly developed staining technique (PPD) for tracing degenerated fibers in the human brain. We applied the PPD method to the chiasmal/hypothalamic area of human autopsy brains from patients who had incurred prior optic nerve damage.

AbstractThe boundaries of subnuclei of the hypothalamic paraventricular nucleus (PVN) were outlined on the basis of a step by step computer‐assisted image analysis of coronal, serial sections of the hypothalamus in rats. The cell size‐frequency histogram, cell packing density, and the cell number were determined for each PVN subdivision.

Modulation of the arterial baroreflex by the hypothalamic paraventricular nucleus.
The FASEB Journal, 2008Previous studies have demonstrated that nonspecific activation or inhibition of the paraventricular nucleus (PVN) alters arterial baroreflex (BR) function. However, the action of specific neurotransmitters is unclear. PVN pre‐autonomic neurons are tonically inhibited by γ‐amino butyric acid (GABA) input.

Circannual Rhythms of Ground Squirrels: Role of the Hypothalamic Paraventricular Nucleus
Journal of Biological Rhythms, 1986Female golden-mantled ground squirrels, maintained in an LD 14:10 photoperiod at 23 degrees C, sustained lesions of the paraventricular nucleus (PVN) or sham operations. Body weight and reproductive status were recorded weekly pre- and postoperatively.

AbstractRecent evidence that 5‐hydroxytryptamine (5‐HT or serotonin) enhances the release and the gene expression of vasopressin and oxytocin in the hypothalamic paraventricular nucleus (PVN) suggests that 5‐HT can excite the PVN magnocellular neurons.

Virgin, ovariectomized rats exposed to 2 wk of sequential estradiol (E2) and progesterone (P) followed by P withdrawal have increased hypothalamic oxytocin (OT) mRNA and peptide levels relative to sham-treated animals. This increase is prevented if P is sustained. In the central nervous system, P is metabolized to the neurosteroid allopregnanolone (3α-
