Orexin activates neurons in the paraventricular nucleus of the hypothalamus
PhysiologyThe paraventricular nucleus (PVN) of the hypothalamus is a critical site for cardiorespiratory homeostasis including reflex sympathetic and respiratory responses to hypoxia. Orexin (Ox)-producing neurons originating from the perifornical hypothalamus project to the PVN.

Metabolic effects of neuropeptide Y injections into the paraventricular nucleus of the hypothalamus
Brain Research, 1990The metabolic effects of single injections of neuropeptide Y (NPY) into the paraventricular hypothalamus were investigated in an open-circuit calorimeter. Wistar rats were tested, with no food available during the tests. Over the dose range of 10-156 pmol NPY had large effects on respiratory quotient (RQ) while having no effect on energy expenditure or

Within the rat paraventricular nucleus of the hypothalamus two types of neurons have been distinguished based on morphological appearance, i.e., parvocellular and magnocellular neurons. The parvocellular neurons play a key role in regulating the activity of the hypothalamo–pituitary–adrenal axis, which is activated, e.g., after stress exposure.

Vasopressin-containing neurons, identified by immunocytochemistry, are located predominantly in the posterior magnocellular division of the paraventricular nucleus of the rat hypothalamus. By electron microscopy, the immunoreaction product is seen within the cell bodies and neuronal processes.

AbstractAdrenergic and noradrenergic neural projections to the paraventricular nucleus of the hypothalamus (PVN) contribute importantly to viscerosensory modulation of pituitary hormone secretion. Immaturity of ascending catecholamine pathways may partially underlie the documented hyporesponsiveness of PVN neurosecretory cells to certain interoceptive ...
