<p><b>(A)</b> Values for mEPSP amplitude (black), EPSP amplitude (gray), and quantal content (QC; white) normalized to wild type (dashed line). No measures were significantly different from wild type. <b>(B)</b> Representative electrophysiological traces for the data shown in A. Scale bar for EPSP (mEPSP) traces: y = 5 mV (0.5 mV), x = 50 ms (1 s). <b>(C and D)</b> Failure analysis of wild type and <i>Csk</i> mutant NMJs. <b>(C)</b> % of total stimulus events that failed to produce an evoked response. <b>(D)</b> Quantal content calculated from failure analysis, QC = ln(# trials/# failures). <b>(E)</b> Calcium cooperativity curve from NMJs of wild type and <i>Csk</i> mutant animals.
