The Soma model simulates the origin of the resting potential in nerve cells. Because this model demonstrates steady-state conditions, or slow changes in the steady state, the membrane capacitance is ignored. In addition, there are no voltage- or time-dependent membrane conductances in this model. The equilibrium (Nernst) potentials for sodium, potassium, calcium, and chloride ions are calculated from the relevant ionic concentrations. The relationship between temperature and equilibrium potentials can be explored by altering the simulated temperature. This model also includes an electrogenic pump, which generates a net outflow of positive ions and therefore acts to hyperpolarize the membrane.

Keywords:   parameter, variable, resting potential, Nernst equation, parallel conductance model, electrogenic membrane pump, conductance
