A: community detection ensemble to muscle correlation: Each ensemble was correlated to an ipsilateral flexor and an ipsilateral extensor EMG. Each point represents the correlations to the flexor (x-axis) and extensor (y-axis) muscles for a single ensemble. Only significant correlation values were included in the analysis (n = 45). The regression is nearly at unity and its location to the right of the unity line indicates that each ensemble’s positive muscle correlation is greater than its negative muscle correlation. B: preferred phase of firing (PPF) ensembles correlation to flexor and extensor EMGs. Analysis as for A.
