White matter tract regions exhibiting significant (clusterwise P < 0.001) positive correlation between FA and motor skill in patients with chronic stroke. (A) Regions in lesion zone. (B) Regions remote from lesion. Shown are clusters in: 1, ipsilesional precentral gyrus; 2, ipsilesional superior corona radiata; 3, ipsilesional superior/anterior corona radiata; 4, contralesional superior posterior limb of internal capsule; 5, ipsilesional middle posterior limb of internal capsule, cerebral peduncle; 6, ipsilesional superior/anterior corona radiata. Clusters shown overlaying mean FA image from patients with stroke.
