Abstract
In a shuttle-box self-stimulation paradigm, analgesic doses of morphine increase the amount of time a rat leaves rewarding brain stimulation on, without altering average OFF times. This paradigm may serve as a model for the euphoria induced by narcotic drugs and as a useful tool for evaluating the reinforcing effects of drugs.Keywords
