Fractional anisotropy (FA) values in reconstructed white matter fiber tracts.

Region of measurement	T1	T2	p*
Lesion tract	0.44 (0.42–0.46)	0.39 (0.37–0.41)	0.008
Mirror tract	0.44 (0.43–0.46)	0.43 (0.42–0.45)	0.712
Interhemispheric tract at corpus callosum	0.67 (0.64–0.68)	0.63 (0.61–0.64)	0.032
V1–V1 tract at corpus callosum	0.69 (0.67–0.72)	0.69 (0.66–0.71)	0.501

Note: Longitudinal results on days 3–5 (T1) and one year after stroke (T2) are shown. See also Figure 1 illustrating areas of measurement. V1–V1 corresponds to interhemispheric fiber tracts connecting primary visual cortices on both hemispheres. *p-values resulting from Mann–Whitney–U-Test between T1 and T2. Significant differences (p<0.05) of FA between T1 and T2 are marked with bold values.
