[Participation of peptides in processes involved in the development of alimentary motivation in the rabbit].

On the base of behavioural and electrophysiological experiments it was suggested that in rabbits the realization of the dominant feeding motivation into the goal-directed behaviour implied at the molecular-genetical level the operative synthesis of gastro-intestinal neuropeptide gastrin or its derivatives. It was supposed that the suppression of genetic information realization in CNS under blocking of peptide synthesis led to impossibility of goal-directed alimentary behaviour organization. This mechanism was found to be specific for alimentary behaviour; any its connection with defensive motivation realization was not observed.
