- 83 Downloads
Two rats on free-reinforcement schedules were injected with doses of d,1-amphetamine or pentobarbital sodium just before sessions. Pentobarbital did not much affect frequency of drinks; amphetamine did. Pentobarbital somewhat limited the maximum length of drinks; amphetamine did noto Both drugs increased somewhat the incidence of very short drinks, relative to longer drinks.
