As described in the Materials and methods section, time dependence of recovery saw fit using a sum of exponentials with the following equation: fraction recovered y = C − Af*exp(−t/τf) − As*exp(−t/τs). Recovery after 10- and 200-ms depolarizing pulses are both shown here. Mean ± SEM of each parameter for sets of three to seven cells are shown.
