a-c: In vivo and ex vivo FA, λ∥, and λ⊥ measured in the caudal corpus callosum at several time points. * indicates significant difference from the baseline values (0 week) with p < 0.05 after correction for multiple comparison. The error bars show the standard deviations of the measurements (n=5 at each time point). d: There is no significant correlation between perpendicular diffusivities measured in vivo and ex vivo in this model.
