Excitation properties of the model of a nerve bundle which included a population of 400 motor nerve fibers. A. Average input-output (recruitment) curve for three different random fiber distributions. B. Average refractory curves for three different random fiber distributions. The amplitude of each pulse in the pair was selected to activate 30%, 60% or 90% of the nerve fibers when delivered as a single pulse, and the interval between the paired pulses was varied.
