#Voxels: number of voxels in cluster. MNI: coordinates in the Montreal Neurological Institute standard brain space. : maximum score in cluster. The percentage of voxels from the cluster falling within the named region is indicated by the superscripted values (obtained by the SPM Anatomy Toolbox). I: ipsilesional; C: contralesional.
