Predominantly phasic neural activity for sustained hand and finger movements in SEEG and ECoG recordings. Representative set of composite temporal responses across three study participants and different hand and finger movements are shown. In both the SEEG (depth) and HD ECoG (surface) recordings, the responses across a wide range of frequency bands are predominantly phasic in nature. The MCC (repeatability metric) was greater than 0.6 for all plots in this figure except in P1_02 where it was 0.5 for “Close hand (SEEG)” and 0.4 for “Thumb Flexion (HD ECoG).”
