Neuroimaging results for: (A) the group main effect, wherein problem stimulant users (PSU) exhibited greater left inferior frontal gyrus (IFG), right anterior insula (AI), and right superior frontal gyrus (SFG) activation than desisted stimulant users (DSU) and healthy comparison subjects (CTL) across anticipation and soft touch trials. PSU also displayed greater activation than CTL in right IFG but did not differ from DSU according to Bonferroni corrections; and (B) the group x condition interaction, wherein PSU displayed higher bilateral precentral gyrus (PCG)/middle insula (MI) activation than DSU and CTL during the soft touch condition but not the anticipation condition. Error bars reflect + 1 standard error of the mean.
