Figure 5.
Whole-brain group deformation-based morphometry analysis of T2-weighted images comparing sham-operated and mTBI animals at day 3 (A) and 28 (B). Brain volume differences between sham-operated and mild TBI animals observed in acute and subacute phases post-mTBI. The mTBI rats showed both volume enlargement (red-yellow color scale), and volume reduction (blue-light blue color scale) compared with the sham-operated rats. The figure shows 1 – p, where p is the permutation-based FWE corrected p value after TFCE enhancement of the test statistic; a corrected p < 0.05 was considered significant.
