We used T1-weighted MRI to compare brain structure in 15 adult TS volunteers and 15 carefully matched tic-free controls. No significant results after correction for multiple comparisons; trend decrease in GM concentration in voxels centered in left precentral gyrus (primary motor cortex) (-26, -12, 66).
