Responding of pigeons was maintained under a multiple fixed interval, fixed ratio schedule of food delivery, and 10 mg/kg morphine was administered daily. Responding during both schedule components was initially decreased and measurable tolerance developed to this effect after four daily injections.

The development of tolerance to behavioral effects of morphine was investigated in rats that responded on a two-lever, multiple-trial, multiple differential-reinforcement-of-low-rate fixed-ratio (mult DRL FR) schedule of food presentation. Stable performances were maintained when sessions were condu
Schedule-controlled responding was maintained under a multiple fixed-interval, fixed-ratio schedule in pigeons. Dose-related decreases in response rates were produced by clonidine (0.00a-0.1mg/kg) and morphine (0.3-5.6 mg/kg). Chronic administration of morphine produced (1) tolerance to effects of m
