Note:—FWE corr indicates family-wise error corrected; L, left; MNI, Montreal Neurological Institute; R, right. k is the number of voxels within each cluster. All clusters of voxels above a voxel-level threshold FWE P ≤ .05 of size k > 2 are shown. For the largest clusters, the table shows up to 3 local maxima more than 8 mm apart. The x, y, and z coordinates are in the MNI space. Peak-t and Peak-z values are within each cluster.
