Fig. 2: Longitudinal changes in the fixel-based metrics over 1 year in patients with progressive supranuclear palsy (PSP) and corticobasal syndrome (CBS).

The streamlines that were cropped from template tractograms passing significant fixels (family-wise error-corrected P < 0.05) are shown as colored by direction: red, left-right; green, anterior-posterior; and blue, inferior-superior, in the longitudinal fixel-based analysis of PSP shown in column (a) and CBS shown in column (b).
