Effects of trial type (go vs. no-go), face emotion (happy vs. sad vs. neutral), and drug (guanfacine vs. placebo) on task-related activation illustrated for regions of interest in prefrontal cortex. Mean parameter estimates of task-related activation were plotted for the significant: a main effects of Trial Type and Face Emotion in right frontal operculum; b Trial type × face emotion interaction in right inferior frontal gyrus pars orbitalis; and c Trial type × face emotion × drug interaction in left dorsolateral prefrontal cortex. Error bars indicate standard error of the mean
