Fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) were computed from diffusion weighted images in the FMRIB Diffusion Toolbox (FDT; FSL; Smith et al., 2004). FA, MD, AD, and RD values for each participants were extracted from the eight ROIs utilized in the MEG analysis and compared between groups.
