The aim of this project was to investigate whether the short-term acquisition of a new force-matching skill is mediated by alterations in the shared synaptic input to spinal motor neurons. For this purpose, we decomposed high-density surface electromyograms from a hand (first dorsal interosseous; FDI) and a leg (tibialis anterior; TA) muscle using this algorithm. We also conducted simulations of entire motor neuron pools to elucidate the neural mechanisms that could explain our results.
