The study of structural asymmetries provides important clues to the neuroanatomical basis of lateralized brain functions.

## Abstract The diffusion tensor (DT) is a three‐dimensional (3D) model of diffusivity in biological tissues. In white matter (WM), the major eigenvector, which is the direction of greatest diffusivity, is generally assumed to align with the direction of the fiber bundles. The distribution of major
