Abstract :
The authors examine several models for cells exposed to EMF where the source of nonlinearity is membrane conductance. These include nonlinear cable and modified Fitzhugh-Nagumo models of cylindrical cells. Membrane response is typically quasi-linear except for combinations of large amplitude and low frequency where the authors observe narrow bands of subharmonic, quasi-periodic, and chaotic behaviour over a range of frequencies
