Diffusion measures in the whole brain white matter (WBWM) vs. age for the control (in black symbols) and sh pups (in red symbols). (a) Po, the zero displacement probability; (b) FA, fractional anisotropy; (c) MD, mean diffusivity; (d) Da, axial diffusivity; (e) Dr, radial diffusivity. Only control pups had significant fits (p-value < 0.05), where the regression lines were plotted in dark blue. Each symbol denotes an individual pup.
