All clusters are reported with p < .05, threshold free cluster enhancement (TFCE) corrected. The table shows the number of significant voxels per cluster, the minimal p value inside the cluster, the MNI coordinates of the voxel with minimal p value, and the location of the cluster (estimated from the Harvard–Oxford Cortical and Subcortical Structural Atlases and the Cerebellar Atlas in FSL).
