[Conditioned reflex reproduction of evoked potentials during reinforcement by electrostimulation of the hypothalamus].
Conditioned evoked potentials to stimulation of a limb, a light flash or a short tone were studied on rats in acute experiments with nembutal anaesthesia and in chronic experiments. Electrical stimulation of the hypothalamus was used as reinforcement. Following the pairings of conditioned and hypothalamic stimulation, the appearance of conditioned EP was recorded, as manifest in the period of the previously applied unconditioned signal after its omission. Their emergence was facilitated after high-frequency stimulation of the hypothalamus or administration of galantamine, an anticholinesteraze drug. Coagulation of the hypothalamus did not prevent any manifestation of conditioned evoked potentials.
