Simplified parametric models of the dielectric properties of brain and muscle tissue during electrical stimulation

Modeling the electric field induced during electrical stimulation is a vital component in understanding how electrical stimulation of nerves can modulate activity of the nervous system. Over the past several decades, it has provided insight into the various effects of electrode geometry, tissue electrical properties and neural response across a range of application areas. In the majority of modelling studies both to assess the efficacy of electrical stimulation and to simulate bioelectric signals, it is assumed that capacitive, inductive and propagation effects can be neglected [1], a simplification known as the quasi-static approximation [1 –3].
