Lesions of the Hypothalamic Paraventricular Nucleus Disrupt the Initiation of Maternal Behavior
Physiology and Behavior, 1989Electrolytic lesions of the paraventricular nucleus (PVN) of the hypothalamus were found to disrupt the initiation but not the maintenance of maternal behavior in primiparous Sprague-Dawley rats. Following lesions performed on Day 15 of gestation, measures of maternal behavior (grouping, crouching, and nest building), pup retrieval, and pup weight gain

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.

Behavioural effects of NMDA injected into the hypothalamic paraventricular nucleus of the rat
Brain Research, 1991Electrical stimulation of the hypothalamic paraventricular nucleus (PVH) and of the adjacent dorsal hypothalamic area (DHA) evokes grooming behaviour. Microinjections of low doses of kainic acid, an agonist of the kainate type of glutamate receptors, into the same area evokes the same behaviour.

Hypothalamic paraventricular nucleus lesions produce overeating and obesity in the rat
Physiology & Behavior, 1981Abstract It has recently been demonstrated that chronic noradrenergic stimulation of the hypothalamic paraventricular nucleus (PVN) or wire knife cuts in the vicinity of the PVN cause hyperphagia and increased body weight. The present study investigates in rats the impact of electrolytic lesions within and around the PVN, on food intake, water intake,

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.

Hypothalamic paraventricular nucleus and cardiovascular regulation.
Clinical and experimental pharmacology & physiology, 20011. The hypothalamic paraventricular nucleus (PVN) is an important integrative site within the brain composed of magnocellular and parvocellular neurons. It is known to influence sympathetic nerve activity. 2. The parvocellular PVN contains neurons that project to the intermediolateral cell column of the thoraco-lumbar spinal cord (IML).
