2. Fig 1
T2-weighted images for patient 1 show (A) high signal intensity in the right primary SM1 including the precentral knob and a portion of the primary S1, which corresponds to the posterior portion of the precentral knob (arrow). (B) The contralateral (right, contrainfarct side) primary SM1 was activated by movements of the unaffected (right) hand. (C) Significant activation during movements of the affected (left) hand was restricted to the contralateral (right, infarct side) S1 and the red line indicates the central sulcus.

3. Fig 2
T2-weighted images for patient 2 show (A) high signal intensity in the precentral knob (arrow) of the right primary M1. fMRI shows that (B) the contralateral (left, contrainfarct side) primary SM1 was activated by movements of the unaffected (right) hand and (C) only the contralateral (right, infarct side) S1 by movements of the affected (left) hands. The red line indicates the central sulcus.
