Nonlinear models of cells exposed to electromagnetic fields

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.
