Separation of the 48 white matter fiber tracts into two groups.

A: Probability map (sagittal, coronal, and axial T1-weighted slices on the brain and axial FA slices in the atlas space at the level of the pons) of belonging to the two different groups for the 48 white matter fiber tracts studied at the level of the population: yellow indicates the highest probability (>80%) of belonging to group 2 (the most injured white matter fiber tracts) and red the lowest probability (<20%) of belonging to group 2. B: Binary affiliation map (sagittal, coronal and axial T1-weighted slices on the brain and axial FA slices in the atlas space at the level of the pons) of the 48 white matter fiber tracts: in green those belonging to group 1, in purple those belonging to group 2, which are medial lemniscus and the left superior cerebellar peduncle. C: Tractography of the white matter fiber tracts that had the highest probability of belonging to group 2: corticospinal tracts (a), medial lemniscus and superior cerebellar peduncles (b).
