Values are given as mean ± standard deviation [n] for fractional anisotropy (FA) or (mean ×1,000) ± standard deviation [n] for radial diffusivity (RD), mean diffusivity (MD), and axial diffusivity (AD). *Effects of group (P=8.21e-05), sex (P=0.000454), litter (P=7.68e-05), and sex-by-litter (P=0.000272) were significant.
