Statistically significant reductions (P < 0.05) of FA are indicated by italic bold. Statistically significant increases of FA are indicated by bold non-italic. Controls were anesthetized and pseudo-blasted. FA values from the two hemispheres were averaged. Number of animals used for ex vivo DTI: n = 3 for Day 2; n = 5 for Day 5; n = 3 for Day 12; and n = 6 for controls.
