A neurophysiological technique of double-pulse stimulation has been applied to freely moving rats with chronic indwelling electrodes in the hypothalamic reward area. Self-stimulation thresholds, measured as a function of the interpulse interval, generated curves with time constants characteristic of refractory periods and temporal synoptic summation. The results indicate a way of studying central neuronal processes for which the overt behavior of the animal is the dependent variable.
