Abstract
Rats were trained to press a lever for the intravenous administration of d-amphetamine. The rate of responding was decreased in a dose-dependent and time-related manner by non-contingent injections of d-amphetamine, methylphenidate or McNeil 4612. Methylphenidate and McNeil 4612 also maintained self-administration behavior when they were substituted for d-amphetamine, whereas substitution of saline for d-amphetamine resulted in extinction of the self-administration behavior. These data suggest that methylphenidate and McNeil 4612, like d-amphetamine, can act as reinforcers in rats.Entities:
