Note: x, y, and z refer to MNI coordinates; t refers to the t-score at those coordinates (local maxima); k refers to the number of voxels in each significant cluster. ACC, Anterior cingulate cortex. VLPFC, ventrolateral prefrontal cortex. Regions with the same superscript signify they belong to the same cluster of activation.
