Estimation of the firing behaviour of a complete motoneuron pool by combining electromyography signal decomposition and realistic motoneuron modelling

Distribution of force recruitment thresholds Fth in the human Tibialis Anterior (TA) muscle and mapping of the Nr identified MNs to the complete MN pool. (A) Typical partition obtained from the literature of the TA MN pool in 10% increments in normalized Fth. (B) Equivalent Fth stepwise distribution (black dots) in a TA pool of N = 400 MNs, approximated by the continuous relationship Fth(j) (red curve). The mapping (blue crosses) of the Nr = 32 MNs identified in the dataset DTA35 was obtained from the recorded (Fig 4B). (C) Nr = 32 MNs (red dots) of unknown properties (Left) are mapped (Right) to the complete MN pool from the Fth(j) distribution, represented by the blue dots of increasing sizes. The MNs represented here are numbered from left to right and bottom to top from j = 1 to
