a Neural activity generated as the participant attempted to move his right hand was recorded from the region controlling hand movements in the participant’s left motor cortex through a 96 channels Utah array. Motor attempts were decoded by a nonlinear support vector machine based on oscillatory power in the multiunit range (234–3750 Hz) for each channel. The decoded movement was executed through a custom NMES sleeve (panel c). Figure 1a was adapted from Serino, A., Bockbrader, M., Bertoni, T. et al.
