PRL-releasing peptide inhibits food intake in male rats via the dorsomedial hypothalamic nucleus and not the paraventricular hypothalamic nucleus.
PRL-releasing peptide inhibits food intake after intracerebroventricular injection. PRL-releasing peptide immunoreactivity is found in several hypothalamic nuclei involved in feeding, with highest levels in the paraventricular and dorsomedial hypothalamic nuclei. The aim of this study was to examine the effect of PRL-releasing peptide on food intake after administration into these nuclei. Parav...
متن کاملStimulation of the hypothalamic paraventricular nucleus modulates cardiorespiratory responses via oxytocinergic innervation of neurons in pre-Botzinger complex.
Previously we reported that oxytocin (OT)-containing neurons of the hypothalamic paraventricular nucleus (PVN) project to the pre-Bötzinger complex (pre-BötC) region and phrenic motoneurons innervating the diaphragm (D). The aim of these studies was to determine pathways involved in PVN stimulation-induced changes in upper airway and chest wall pumping muscle activity. In addition, we determine...
متن کاملHypothalamic Paraventricular Nucleus Modulates Sympathetic Excitation
Aldosterone stimulates the sympathetic nervous system by binding to a select population of brain mineralocorticoid receptors (MR). These MR have an equal affinity for corticosterone that is present in substantially higher concentrations, but are held in reserve for aldosterone by activity of the enzyme 11 -hydroxysteroid dehydrogenase type 2 (11 -HSD-2), which converts corticosterone to an inac...
متن کاملOrexin depolarizes rat hypothalamic paraventricular nucleus neurons.
Orexins, also called hypocretins, are newly discovered hypothalamic peptides that are thought to be involved in various physiological functions. In spite of the fact that orexin receptors, especially orexin receptor 2, are abundant in the hypothalamic paraventricular nucleus (PVN), the effects of orexins on PVN neurons remain unknown. Using a whole cell patch-clamp recording technique, we inves...
متن کاملLeptin depolarizes rat hypothalamic paraventricular nucleus neurons.
Leptin, 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. Using patch-clamp recording techniques, this study examines the direct membrane effects of leptin on neurons in a co...
