Mean number of 1-g food pellets per day produced by four baboons during the evaluation of self-administration of TPA123, TPA023, and lorazepam. Food pellets were available 24 h/day under an FR-20 schedule of reinforcement. Data are for the same periods of time as the self-injection data in Fig. 2. For the individual baboons, vertical bars around the vehicle (V) means indicate 1 S.D., and those around group means represent 1 S.E.M. Bars were omitted around the drug dose means for individual baboons for clarity. Pellet data for 0.056 mg/kg TPA123 were omitted for LC because pellet intake dropped and he received supplemental food.
