title: Tripelennamine: enhancement of brain-stimulation reward.
abstract: Thresholds for reinforcing electrical stimulation to the medial forebrain bundle were determined in rats by means of a rate-free psychophysical method. The acute administration of tripelennamine lowered the threshold for rewarding brain stimulation in a dose-dependent manner. These results suggest that the abuse liability of tripelennamine may be related to its ability to sensitize the central neural pathway that mediates reward.
