Membrane capacitance and correction of end-plate potentials for nonlinear summation of quantal units

The question of effect of muscle membrane capacitance on Martin's correction of end-plate potential amplitudes for nonlinear summation of unit potentials was examined. By addition of capacitance to the membrane circuit model which serves as the basis for the correction, it is demonstrated through use of the appropriate circuit equations that the correction is unaffected by capacitance.
