Activation during the feedback phase. (A) ROI‐based Comparison between Gains versus No Gains in the Feedback Phase. Scatterplot of NAc values for the contrast of Gains > No Gains from ROI analysis. There was a trend‐level interaction between group and activation to reward, with MJ showing slightly larger increases in response to gains than controls. (B) Voxelwise Comparison between Gains versus No Gains in the Feedback Phase. Both groups demonstrated significant activation of the NAc during notification of gains. Images are thresholded at P < 0.01, uncorrected. The localization of activation during the feedback phase was posterior in the NAc relative to activation related to the choice phase.
