Hypothalamic paraventricular nucleus: A quantitative analysis of cytoarchitectonic subdivisions in the rat

Journal of Comparative Neurology, 1991
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, 2008
Previous 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, 1986
Female 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.

Inhibition of gastric motility induced by activation of the hypothalamic paraventricular nucleus

Brain Research, 1985
Electrical stimulation of the paraventricular nucleus depressed the intragastric pressure of adrenalectomized male rats of which gastric movement had been induced by insulin-hypoglycemia. Electrical stimulation to the pituitary stalk produced a similar response in the pressure, but the response was abolished by bilateral lesion of the paraventricular ...

Hypothalamic paraventricular nucleus and cardiovascular regulation.

Clinical and experimental pharmacology & physiology, 2001
1. 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).
