  1. BOLD activation areas: BOLD activation areas elicited by contralesional hand or foot movement. Stimulation positive sites: Positive sites of electrical stimulation. Post-operative motor deficit: muscle strength of hand and/or foot contralateral to lesion hemisphere
  2. PMA primary motor area, SMA sensorimotor area, SA sensory area, SPL superior parietal lobule, AMA anterior motor area, U: unavailable
  3. * labeled the peak motor activity point
