title: [Effect of neurohypophyseal peptides on the formation of a conditioned feeding reflex in the rat].
abstract: The influence of intraperitoneal injection of vasopressin (LVP), oxytocin (OXY) and their fragments (DGAVP, PLG) on the acquisition and extinction of conditioned food reflex was studied in rats. It was found that vasopressin and its fragments had a more pronounced specific effect on the higher nervous activity of the animals. This effect consisted in impairment of the performance of the conditioned food reflex while oxytocin had a tendency to improve its performance. On the ground of the obtained data it is suggested that administration of vasopressin may facilitate the memory function only under specific environmental conditions.
