[Motivation and reinforcement in the systemic mechanisms of behavior: the dynamic engrams of reinforcement].

Theoretical and experimental data are presented which give evidence that in systemic organization of behaviour motivation and reinforcement interact in separate brain neurons. It has been shown that the immunity mechanisms participate in motivation-reinforcement interaction. It is postulated that in the process of learning the reinforcement by means of feedback afferentation forms molecular engrams on the neuronal structures of action acceptor. Such engrams are built by DNA and protein synthesis in ribosomes. Later on these engrams can be activated by the dominant motivation.
