The effects of morphine pellet implantation and naloxone administration were examined in rats lever pressing under inter-response time schedules of food presentation. Subcutaneous implantation of a morphine pellet initially decreased lever-pressing rates. Tolerance to this effect developed within 3-

Phencyclidine (PCP), haloperidol, and naloxone were administered alone and in combination to rats responding under a fixed-interval schedule for water presentation. Lower doses of PCP (0.25-2.0 mg/kg) and naloxone (0.001-0.1 mg/kg) produced increases while higher doses produced dose-dependent decrea
The effects of morphine (10 mg/kg), nalorphine (1 and 10 mg/kg), and naloxone (1 mg/kg) were studied on the neoeortical release of aeetylcholine (ACh) in midpontine pretrigeminal transected rats. Morphine and, to a lesser extent, nalorphine decreased ACh release. Naloxone was ineffective alone but a
The capacity of the specific narcotic antagonists naltrexone and naloxone to block the discriminative effects produced by morphine in the rat were evaluated using a two-choice, discrete-trial avoidance task. The antagonists produced a dose-dependent and time-dependent blockade of morphine's effects
