High-resolution neuroprosthetic decoding of finger movements and hand gestures could greatly improve the usability of robotic limbs and enable new communication methods such as typewriting. Here, we aimed to understand the motor cortical neural activity during naturalistic hand gestures, to guide the design of hand motion neuroprostheses. Simultaneous neural population activity was recorded from two intracortical Utah arrays (192 channels) in the ‘hand knob’ area of left premotor cortex of a participant with tetraplegia (‘T5’) while he attempted different hand gestures. Trials varied across
