Conjunction map of task-related brain activity during reward processing. Task-related activity maps for each group at each study visit (baseline and revisit) were voxel-thresholded at p < 0.05 and a conjunction map was created for Win > No Win brain response to determine areas commonly activated across participants regardless of group status or time of study visit. Occipital, superior parietal, dorsolateral prefrontal, caudate, and ventral striatal brain activity were seen in the Win > No Win contrast overlaid on AFNI's Talairach template brain in the axial view.
