Nerve excitation model for localized magnetic stimulation of finite neuronal structures

We focus on a membrane excitation model of finite and bent nerves elicited by magnetically induced electric fields. We simulated nerve excitation by changing the length of an axon and the distance between the coil and the nerve. The computer simulation suggests that the termination points of nerves or the bending part of an axon are low threshold stimulation sites when magnetically stimulated with a figure-eight coil. We also suggest that a short axon is more easily excited than an infinitely long axon of the same thickness. These results give useful information in understanding neuronal responses to magnetic stimulation of both central and peripheral nervous systems.
