Simulation of the Wave of Action Potential Propagation over the Length of the Axon at Various Times by Comsol Multiphysics Software

In this study, simulation of Fitzhugh nagumo model in order to generation and propagation of the wave of action potential over the length the of the squid giant axon and survey the passage of time effect in wave propagation have been explored. Simulation has been performed by using the Comsol Multiphysics 3.5 a software. So that, in this simulation, squid giant axon is intended to form hollow cylinder. For this purpose PDE (general form) module have been used. Then by running the simulation steps, we see that the wave of action potential along axon at different times released and from the beginning to the end of the axon is transmitted. Thus, nerve signals are transmitted between different organs.
