LHAad PNN/ECM degradation does not block cue-induced reinstatement of sucrose seeking. a Timeline of the experiment. b SA active lever presses, c SA reinforced lever presses, d EXT active lever presses, e SA inactive lever presses, and f EXT inactive lever presses. g Active lever presses in the first 30 min of the last extinction session compared to the 30 min cue-induced reinstatement session, and h inactive lever presses during the 30 min cue-induced reinstatement session (Data are mean ± SEM). Differences were considered significant when *p < 0.05. i Injection sites in sucrose trained animals that received intra-LHAad microinjection of vehicle (black circles; n = 7) and Ch-ABC (gray circles; n = 8)
