Abstract
1.
1. Male hooded rats were trained to discriminate the anxiogenic action of phentylenetetrazol by responding for food reinforcement with a lever located on one side of a food cup 15 min following a 20 mg/kg pentylenetetrazol injection and responding with the lever located on the alternate side of the food cup 15 min following a 1 ml/kg saline injection.
2.
2. Cocaine (20 mg/kg) but not diazepam (5 mg/kg) nor haloperidol (0.16 or 0.64 mg/kg) significantly generalized to the pentylenetrazol discriminative stimulus.
3.
3. Diazepam (5 mg/kg) but not haloperidol (0.16 or 0.64 mg/kg) significantly antagonized the discriminative stimuli produced by pentylenetetrazol and cocaine.
4.
4. These data suggest that cocaine produces discriminative stimulus that is related to its anxiogenic action.
