Human corticospinal tract lateralization at the height of the internal capsule is not related to handedness [PDF]
Scientific ReportsEvaluating the integrity of the corticospinal tract at the height of the posterior limb of the internal capsule with a lateralization index has been applied to predict upper limb motor recovery after stroke in numerous diffusion tensor imaging studies ...
