Results of diffusion tensor imaging data processing (single slice, representative patient). Left: Map of the direction of the diffusion tensor’s principal eigenvector (V1). The luminosity denotes the fractional anisotropy (FA) value. Middle: Map of the mean diffusivity (MD). Right: Map of FA. MD is given in units of 10–3 mm2 s–1. In the MD and FA maps, the light blue lines indicate the pial surface, and the dark blue/red lines the white matter surface, as identified with Freesurfer.
