Quasi-Linear ICA for Motor Unit Decomposition during Dynamic Contractions

ArXi:2406.19581v2 Announce Type: replace-cross Decomposing surface electromyography (EMG) into the spike trains of individual motor neurons is a long-standing inverse problem and a key step toward motor-neuron-driven neural interfaces such as prosthetics and exoskeletons. The standard approach, independent component analysis (ICA) of the multichannel signal, assumes that the mixing from neurons to electrodes is stationary in time.
