Note. Investigating error-related processing in the contrast False Alarms (FA’s) vs. Hits. Coordinates are given in MNI space. Results were small-volume peak corrected for the ROI (FWE-corrected). No significant associations were found with ROIs and age or number of substance dependencies. Analyses performed with n = 182 participants.
