Dipole Density for Tic and Control groups. Pictures on left show Combined dipole density in brain from sagittal, radial and axial views. Percent of dipole density is presented by group and combined. Top regions overlapped by 70%, however the healthy control (HC) group had more frontal regions (60%) and Chronic Tic Disorder (CTD) group had more posterior regions (80%) with the highest dipole density. L = left, R = right, Supp = supplemental, Sup = superior, Ant = anterior.
