The region in which the cluster’s local maximum is located in hemispheres Right (R), Left (L), or Central (C); peak location in MNI coordinates (x, y, z); cluster extend in number of voxels (k); the maximum Z-score; and FWE-corrected p-values (cluster level corrected,
*
small volume corrected) are reported for each significantly activated cluster separately. IFG, inferior frontal cortex. SMA, supplementary motor area.
