Figure 2.
Figure 2. STOC decay reflects the kinetics of BK channels. (A) No correlation between signal mass (SM) and STOC decay (left; r = 0.0091, P = 0.9588, n = 35) and between STOC amplitude and STOC decay (right; r = 0.3227, P = 0.0587, n = 35). The parameters were calculated from the data shown in Fig. 1. (B) A long recording of STOCs at 0 mV. Arrows depict the time when the events in the inserts occurred. Note that STOCs with different amplitudes can be fitted with a single exponential (solid red lines) with similar time constants. (C) Scatter plot of STOC amplitude and decay for the events from B (left). Mean data reveal that, except for the STOCs in the largest quartile, STOC decay is independent of its amplitude (right). *, P < 0.05 compared with other groups, t test after ANOVA; n = 8 cells.
