Collected results of the time delay of voltage at the cell membrane relative to command voltage. The delay was measured either by aligning muscimol-evoked currents (as in Fig. 1, black circles) or by aligning the action potential voltage command with the altered sodium reversal potential (as in Fig. 2, gray squares). The measured delays shown were corrected for the 40 μs delay arising from the low-pass Bessel filter. The delay was found to be correlated with the residual series resistance remaining after partial series resistance compensation. The solid line is the best-fit linear relationship.
