  1. Cluster size = number of voxels; x, y, z = Coordinates (in mm) of significant local maxima are given for information in MNI space (Montreal Neurological Institute, http://www.bic.mni.mcgill.ca). Significant local maxima more than 8 mm apart were translated to brain anatomy by converting their coordinates from MNI space to Talairach space http://www.talairach.org/ allowing for a search radius of 9 mm for nearest gray matter. For regions where an effect was hypothesized (see introduction), a small volume correction (SVC) was performed. P values are given after family wise error (FWE) correction for the particular volume. No regions displayed significant regional increases in GMV for TS patients versus controls.
