This paper proposes a FEM model for a segment of a nervous cell axon, which takes into account, through the so called Hodgkin-Huxley equations, the non linear and time varying dynamics of the membrane surrounding it. A combination with Maxwell equations is performed in a numerical procedure implemented in the COMSOL Multiphysics® environment. A thin layer approximated alternative model is presented too, which proves to reduce calculus burden. Results are shown demonstrating a very good agreement with literature data for both the proposed approaches.
