All values are means ± SEM for two open and five closed exponential components (EO1–EO2 and EC1–EC5, respectively) fitted by the maximum likelihood method to dwell-time histograms from 8 (20°C; as in Table I, reproduced here again to facilitate comparison) and 13 (30°C) single-channel patches at 100 mV. The mean values have been compared using the Mann-Whitney test (*, P < 0.05; **, P < 0.01). These averaged values should not be used to calculate Po and mean open- and mean closed-time values. Rather, the separate values should be calculated for each channel and then averaged.
