Positive (negative) values denote an increase (decrease) in the diffusion measure relative to the uninjured contralateral WM (columns 1 and 2) or relative to the lesion 3 days after axotomy (column 3).
denotes significant difference (p < 0.01) for the ROI analysis presented in Figures 2B, 3B and 4B.
