P_O, single-channel open probability; τ_O, mean open time; τ_O,COR, mean open time corrected for missed events (Proks et al., 2001); τ_Bi and a_Bi, burst durations and their corresponding amplitudes in the distribution of burst lengths (i = 1–3); τ_B, mean burst duration; np, not present in the distribution. Data are expressed as mean ± SEM (n = 3 each).
