Intra-IL D2 receptor blockade via sulpiride does not alter cued or cocaine-prime reinstatement. A–C, The active lever presses and, D–F, inactive lever presses for each reinstatement test for Experiment 2 are shown. A, Intra-IL microinjections of the D2 receptor antagonist sulpiride had no effect on cued reinstatement (n = 14). B, Intra-IL microinjections of sulpiride had no effect on cocaine-prime reinstatement (n = 13). C, Intra-IL microinjections of sulpiride had no effect on cued + cocaine-prime reinstatement (n = 12). D–F, There were no effects of reinstatement or microinjections on inactive lever presses for any type of reinstatement. *p < 0.05 compared with extinction baseline. EXT, extinction baseline.
