MNI = Montreal neurological institute; GM = gray matter volume; FC [] = functional connectivity [seed region]; C. = cerebellum; L. = left; R. = right cluster size is in voxels; CSA = cross sectional area; Labels are derived from the Harvard-Oxford Cortical Atlas [42] and the SUIT cerebellum atlas [43]; Only local maxima with at least 1cm distance are listed
