case_images: Subject P1 (male, 14 years old), P2 (male, 30) suffered from intractable epilepsy, and they underwent temporary placement of a subdural electrode array in order to localize the epileptic seizure focus and map brain function prior to surgical resection (Figure 1B).
case_images: The full run experiment of subject P1. T1, hand unfold; T2, hand grasp; T3, thumb-finger motion; T4, wrist motion; T5, index-finger motion. Each trial lasts 5 s, thereby 50 s were needed for the full run.

case_images: Each run contained 5 trials which indicated different hand motion types (Figure 2), i.e., hand unfold (T1), hand grasp (T2), thumb-finger motion (T3), wrist motion (T4), and index-finger motion (T5).
case_images: Full run experiment of subject P3, P4. RUN I, hand grasp; RUN II, thumb-finger motion; III, index-finger motion. Each run contained 20 trials, each trial lasts 4~6 s.

case_images: Three motion types were performed in separate run (Figure 3), i.e., run I for hand grasp, run II for thumb-finger motion and run III for index-finger motion.
