Orexin 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...

متن کاملFeeding inhibition by urocortin in the rat hypothalamic paraventricular nucleus.
Ventricular 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 feeding. We compared the effect of equimola...
متن کاملOrganotypic slice culture of the hypothalamic paraventricular nucleus of rat
Organotypic slice cultures have been developed as an alternative to acute brain slices because the neuronal viability and synaptic connectivity in these cultures can be preserved well for a prolonged period of time. This study evaluated a stationary organotypic slice culture developed for the hypothalamic paraventricular nucleus (PVN) of rat. The results showed that the slice cultures maintain ...
