Early attempts to characterize the electrical properties of excitable membranes utilized alternating current impedance measurements on the giant axon of Loligo and the excitable cell from Nitella. Transverse impedance measurements on both of these systems in the resting state gave data that was interpreted as arising from a membrane capacity (Cm) of approximately 1μ.F/cm2 in parallel with a membrane resistance (Rm) on the order of 103 ohm-cm2 (Curtis and Cole 1938; Cole and Hodgkin, 1939).
