Abstract
In a shuttle box, 8 rats with electrodes in 6 different rewarding brain areas alternately turned the stimulation on and off. Latency of stimulation termination and latency of next onset were decreasing functions of stimulus intensity. Decreasing onset latencies suggest that long durations of stimulation may not be punishing. In another experiment, 5 rats were trained to press a lever for brain stimulation reward on a progressive ratio schedule. Four of the rats were tested on durations ranging from 0.15 to 10.0 sec. and a 5th rat was tested on durations as long as 120 sec. In each of these animals, the number of responses in the final reward ratio run was an increasing function of intensity.Keywords
