โฆ Synopsis
The ability of CNS stimulants to block the discriminative effects ofpentobarbital was studied in pigeons trained to discriminate IM pentobarbital (5 mg/kg) from saline. Pentobarbital, when administered alone, consistently produced greater than 90}' 0 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.

After initial exposure to 80 mg/kg, pigeons trained on a two-key drug discrimination procedure rapidly learned to discriminate 120 mg/kg ethosuximide from saline.

Pigeons trained under a two-key drug discrimination procedure eventually learned to discriminate 5 mg/kg phenytoin from saline injections. When 1.25-20 mg/kg doses of phenytoin were substituted for the training dose, the percentage of responses directed to the phenytoin-appropriate key varied direct
