Initial characterization of intramembrane charge movement currents. a Non-linear difference currents between test pulses to the indicated membrane potentials and corresponding control pulses covering a membrane potential range negative to the holding potential. Same protocol as in Fig. 1. Pulse duration was decreased for the two largest depolarizations displayed. b Equality of charge moved during the “on” and “off” of different amplitude test pulse depolarizations. c Voltage dependence of non-linear charge moved for test pulses to the indicated membrane potentials.
