Abstract:
The paper extends a mathematical model for point-source electrical stimulation of a nerve. In the original model, it was assumed that all the axons in the nerve have the same diameter. In this paper the model is extended to represent a nerve with an arbitrary distribution of axon diameters. It is shown that the assumption of identical axons is justified for a typical human nerve if the 'representative' axon diameter is taken as the area-weighted average of the diameter distribution.
