Mean (SD) values for tract-averaged mean diffusivity (〈D〉) and fractional anisotropy (FA) for the eight fasciculi-of-interest for all 90 subjects and gender groups (51 male). Bold type indicates significant differences between gender groups as assessed using independent samples t tests (p < 0.05). The units of 〈D〉 are μm2 s−1.
