Voltage dependence of spikes. A Voltage responses of an RPE cell at resting potential after a series of 100-ms conditioning hyperpolarizing pre-pulses. B Isolated spikes from A, with asterisks indicating the correspondence between spikes in A and B. C Dependence of spike amplitude, time to peak and half-width on the pre-pulse voltage; data from A and B. D Comparison of the average half-inactivation potentials from SSI recordings and the average half-maximal amplitude potentials for spikes (both denoted with V0.5) in the same cells; the voltage dependencies were fitted with a sigmoidal equation (Additional file 2: Table S1).
