[Peptidergic control of electrical activities in the magnocellular neurons of the hypothalamus].
Although many peptides have been reported in the vicinity of hypothalamic magnocellular nuclei, their role in the control of neurohypophysial hormone release was only studied for few peptides: opiates, angiotensin II, substance P, CRF, oxytocin and vasopressin. Their effects are briefly recalled and then compared to the more detailed study of their role in the firing pattern of oxytocin and vasopressin neurones. This technique, in some cases, revealed the action site and mechanism of these peptides in the hypothalamo-neurohypophysial system.
