Rats were implanted with permanent electrodes in the medial hypothalamus, an area where the duration of electrical stimulation seems the main determinant of the centrally-elicited reinforcing effect, with brief stimulation yielding reward and prolonged stimulation yielding punishment. The reinforcing effect in this study was made as purely punishing as possible by applying stimulation to the hypothalamus continuously. When stimulus intensity was varied in a self-adjustment situation, Ss readily learned to press a lever to regulate the intensity of the continuously applied stimulus. Thresholds of the centrally-elicited aversive effect were thereby estimated, and these thresholds proved to be highly resistant to adaptation or fatigue effects from prolonged stimulation. |
