Figure 3.

Large and small spontaneous release events show similar kinetics. (A) Average uniquantal (small black trace; n = 97) and multiquantal I_A(glu) events (large black trace; n = 20) from a single rod are shown. There were no kinetic differences between the two after scaling the average uniquantal event (red trace, right axis) to match the amplitude of the average multiquantal event. (B) Graph of individual I_A(glu) event amplitudes plotted against 10–90% time to rise. The slope of the linear regression (dotted line) did not differ significantly from zero (F-test; p = 0.28). (C) Average uniquantal mEPSC (small black trace, n = 38) and multiquantal mEPSC (n = 16) from a single horizontal cell are shown. Scaling the uniquantal event (red trace, right axis) to match the amplitude of the larger event revealed that rise times of the two events were equivalent.
