    Abstract:
    Interrelations between motivational and reinforcing components of self-stimulation (SS) zones were studied under stimulation by rhythmic and direct current (RC, DC) of both one and the same zone of self-stimulation and during simultaneous stimulation of two distant SS zones. It was shown that the reinforcing component of SS zones, independently from the way of its activation, has an inhibitory influence on the motivational reactions evoked by a stimulation of the same zone as well as any other SS site. Motivational component depending on the way of its activation has either an enhancing (RC) or an inhibitory (DC) effect on the reinforcing component. The methodical advantage of DC over RC is that DC allows to reveal more distinctly competitory relations between motivational and reinforcing components (in the form of inhibition of SS reactions of other brain points) and synergic relations--between the reinforcing components (in the form of enhancing SS reactions of other brain points).
