Mean (±SEM) active lever (upward bars) and inactive lever (downward bars) responses on the final day of cocaine self-administration, 1st day of extinction, 12th day of extinction and the cocaine-priming-induced reinstatement test session. Open bars represent the group receiving vehicle pretreatment 30 min prior to the 17 mg/kg i.p. cocaine priming reinstatement test session. Gray bars represent the group receiving 1 mg/kg i.p. buspirone pretreatment. Black bars represent the group receiving 3 mg/kg i.p. buspirone pretreatment. * indicates significant reductions in responding on the reinstatement test session (p<0.05) relative to the vehicle control group. n=12/group.
