Abstract : This work has dealt primarily with some of the behavioral effects of brain-stimulation reward, in contrast with the more usual emphasis on physiological and anatomical correlates. A technique was developed assessing reward value; the technique involves the use of a 2-member behavioral chain in which a schedule of reinforcement is programmed on one response lever, and selfstimulation is programmed on another response lever. The second, stimulation lever is not accessible to the rat until the programmed response requirement on the first lever, is completed. Performance characteristics on the first lever, free of the side effects of brain stimulation per se,reflect the behavioral reward value of the second chain member. It was found that sub stantial behavior output can be maintained on the first lever if twenty to thirty stimulation-reinforced presses are permitted on the second lever. The report presents results with regard to those variables and describes findings in experiments designed to make a direct comparison between food and brain-stimulation reward. (Author)
