Identification of the vasopressin-neurophysin producing neurons of the rat suprachiasmatic nuclei

Abstract
Immuno-enzyme histochemical investigations on the hypothalamus of the normal rat showed (1) that the Suprachiasmatic nuclei produce vasopressin; (2) that it is highly probable that these nuclei do not produce oxytocin. From the present and previous investigations it may be concluded that the Suprachiasmatic neurons produce a vasopressin-neurophysin complex.
