Individual- and group-level BOLD fMRI analyses
On the first-level the SID task was modeled in line with previous studies (2, 60-62), including condition- (social reward, social punishment, neutral) and phase- (anticipation, outcome) specific regressors (see supplementary method ). On the group level effects of treatment were examined employing mixed ANOVA analyses with the factors (condition, treatment) for each phase. Based on our a priori regional hypotheses the analyses focused on the ventral striatum (VS), dorsal striatum (DS) (63) and VTA (64) as Regions of Interest (ROIs).
