Note: L—left, R—right, PM—parametric modulator, MCC—midcingulate cortex, ACC—anterior cingulate. The t-values stand for the t-score at the peak activation level and k values refer to the number of activated voxels in activation clusters. Brain regions were based on whole-brain analyses using multiple comparison threshold of a minimum cluster size of 84 voxels (voxel-wise threshold of P < 0.001; 2-sided), corresponding to P < 0.05, family-wise error corrected.
