Analysis of asynchronous miniature EPSCs from individual lemniscal fibers. A, Representative traces of pure AMPAR-meditated asynchronous miniature EPSCs evoked by single lemniscal fiber stimulation in the presence of 4 mm Sr²⁺ ions. B, Averaged traces of asynchronous miniature EPSCs. Traces of 1517, 1341, and 1015 events from 12, 8, and 7 cells were averaged, respectively, for sham fiber (broken line), S-fiber in the IONC group (gray line), and W-fiber in the IONC group (black line). D, The same data as in B, but normalized by amplitude. C, E, F, Mean cumulative probabilities of amplitude, decay time constants, and 10–90% rise time, respectively. Data are represented as the mean ± SEM.
