At trial start, the subject attempts to grasp a foam puck. An LSTM decoder infers the attempted aperture based on signals from M1. Upon object contact, the output of sensors on the thumb and index finger drives ICMS according to a single-electrode linear algorithm or a multielectrode biomimetic one. Linear feedback is delivered through a single electrode, biomimetic feedback through a quartet with overlapping PFs (as in this schematic).
