WebAug 1, 2024 · We hypothesised that music-cued, left-handed motor training would increase fractional anisotropy (FA) in the contralateral arcuate fasciculus, a fibre tract connecting … Fractional anisotropy (FA) is a scalar value between zero and one that describes the degree of anisotropy of a diffusion process. A value of zero means that diffusion is isotropic, i.e. it is unrestricted (or equally restricted) in all directions. A value of one means that diffusion occurs only along one axis and is fully … See more A Diffusion Ellipsoid is completely represented by the Diffusion Tensor, D. FA is calculated from the eigenvalues ($${\displaystyle \lambda _{1},\lambda _{2},\lambda _{3}}$$) of the diffusion tensor. … See more This can be visualized with an ellipsoid, which is defined by the eigenvectors and eigenvalues of D.
