Microinjection of CHPG into the NAcore potentiated cue-induced reinstatement of cocaine-seeking. SA and EXT represent averaged number of active lever presses within last 3 day self-administration training and within last 3 day extinction training, respectively. CHPG (6 µg/side) alone increased the reinstatement of cocaine-seeking and also potentiated cue-induced reinstatement. *p < 0.05, compared with the EXT using a Bonferroni multiple comparisons. #p < 0.05, compared with aCSF injection (0 µg/side). Animal number for each treatment is indicated in the bar.
