MTEP infusion into the NAcore inhibited cue- and cocaine-reinstated drug seeking. (A) Number of active lever presses within last 3 day self-administration training (SA) and within last 3 day extinction training (EXT), as well as after the administration of MTEP (1 µg/side). (B) Attenuation of cocaine-primed reinstatement by MTEP (0.3 µg/side) and of cue-induced reinstatement by MTEP (1 µg/side). *p < 0.05, compared with aCSF treatment. Animal number for each treatment is indicated in the bar.
