| models.motoneuron.Model.FibreTypeDepMaxMeanCurrent = true |
Flag that determines if the mean current parameter is constrained depending on the fibre type parameter.
The actually applicable parameter domain of fibre_type and mean_current is not a square if only "useful" frequencies in the range of 10-60 Hz are required.
An experimentally determined polynomial is used to limit the mean_current.
Default: true
