Abstrakt: The ability of CNS stimulants to block the discriminative effects of pentobarbital was studied in pigeons trained to discriminate IM pentobarbital (5 mg/kg) from saline. Pentobarbital, when administered alone, consistently produced greater than 90% pentobarbital-appropriate responding. The concomitant administration of pentobarbital and increasing doses of bemegride or pentylenetetrazol resulted in a dose-related decrease in pentobarbital-appropriate responses. In contrast, picrotoxin, another CNS stimulant, had little or no effect on pentobarbital-appropriate responding produced by pentobarbital. [ABSTRACT FROM AUTHOR]
