Topographic analysis of areas of negative and positive reinforcement in the central grey matter of the rat (author's transl)

Utilization of a movable electrode has permitted an analysis of areas of negative reinforcement (switch-off response) and areas of positive reinforcement (self-stimulation responses), as well as the behavioral effects of a simultaneous activation of systems of negative and positive reinforcement at the ambivalent sites of a junction-area. Within the areas of reinforcement, gradients were uncovered in the rates of both switch-off and self-stimulation responses.
