Alignment of the diffusion tensors with the gyral coordinate system over 29 subjects in the upper cortex (i.e. more than 1 mm above the white/grey matter boundary. A) Spherical heat map of the orientation of the primary (left), secondary (middle) and tertiary (right) eigenvector of the best-fit diffusion tensor. B) Histogram of the radial (red), sulcal (green), and gyral (blue) diffusion coefficient as predicted by the tensor model averaged over 29 subjects. C) Radial over tangential diffusion of the diffusion tensor averaged for 29 subjects after projecting the diffusion tensor in gyral coordinates onto subject-specific surfaces (overlays of Brodmann areas 3 and 4 from Fischl et al. 2008 and Van Essen et al. 2012). D) Detail of Brodmann areas 3 and 4.
