Figure 4.
Alignment of the primary (top), secondary (middle), and tertiary (bottom) eigenvectors of the best-fit diffusion tensor with the gyral coordinates (red: radial; green: sulcal; blue: gyral) overlaid on a T1-weighted map. Left-most two panels: single subject; right-most panels: average of 29 subjects in MNI space. We excluded voxels that were more than 4 mm below the white/grey matter boundary or were closer to the medial wall than to the white/grey matter boundary.
