Z-statistic maps were thresholded using cluster-corrected statistics with a height-threshold of Z > 3.1 and cluster-forming threshold of p < 0.05.

^ax, y, z reflect coordinates (mm) for peak voxel or other local maxima in MNI_152 space.

^bClusters are numbered and presented in order of decreasing size.

^cL and R refers to left and right hemisphere.
