Spatial profile of the FA changes along the CST for low responders (pink) and high responders (purple), shown in mean ± standard error. The statistical significance of the difference between the two groups was indicated by the color bar (the same scheme as in Fig. 2). Subjects with more substantial motor function improvements showed increased FA after treatment, and the differences were diffusely distributed along the CST, primarily between the internal capsule and the corona radiata.
