Cocaine evokes increases in NAc dopamine signaling. While 10 cocaine infusions significantly (***p<0.0001) increases dopamine signaling (expressed as Average CV Matches) in both the NAc core (n=13, blue bars) and shell (n=14, gold bars), the NAc shell is more responsive to the dopamine-evoking effects of cocaine (**p<0.001). Bars represent group means for the 4 minutes preceding cocaine infusion (cocaine infusion 0) or binned (1–10) cocaine infusion periods. Error bars are ± 1 standard error of the mean (SEM).
