All activations are significant at p < .001 (uncorrected; t > 3.93; cluster threshold > five voxels), which corresponds to a whole-brain alpha of <.05 based on a Monte Carlo simulation conducted with AFNI's AlphaSim. The cluster's Brodmann's area (BA) and the coordinates (MNI space, in millimeters) and t value of each cluster's peak voxel are provided.
