title: [Effect of the "memory peptide" ACTH 5-10 on the self-stimulation reaction of rabbits].
abstract: Experiments on rabbits were made to study variation in the frequency of the self-stimulation reaction from the lateral hypothalamus under the effect of the corticotropin fragment ACTH5-10. Intraperitoneal administration of the peptide in a dose of 50 micrograms/kg that causes the improved training in different behavioral models produces no significant effect on the mechanism of intracranial positive reinforcement. Intraventricular injection of 5 microliters of 0.9% NaCl leads to a short-term suppression of the self-stimulation reaction. Administration of 50 pcM/kg ACTH5-10 in the same volume of physiological saline completely abolishes the inhibitory action of the intraventricular injection itself.
