Activations with greater than 10 contiguous voxels reported, thresholded at p= .05. R = right; L = left; BA = Brodmann’s Area; Coordinates are in Talaraich-Tournoux space; x, y, z coordinates refer to left/right (x: negative = right), anterior/posterior (y: negative = anterior), and inferior/superior (z: negative = inferior); Max t indicates t score at the peak activation of each loc; Vox indicates number of voxels in cluster; d indicates effect size (Cohen’s d).
