Figure 1. Experimental Timeline and Behavioral Results.

(a) Timeline of the experimental procedures. (b) Comparison of cocaine infusions earned during self-administration between groups that would later be assigned to the cocaine cue memory reactivation (n=9), extinction (n=8), or no manipulation control groups (n=7). No significant differences were observed between groups. (c) Comparison of active lever presses during instrumental extinction between groups later to be assigned to memory conditions listed in (b). No significant differences in extinction learning were observed between groups.
