mEPSP frequency in wild-type and brp-mutant NMJs. All brp mutants had one copy of the indicated mutant allele over the corresponding second-chromosome deficiency BSC29. All brp mutants show elevated mEPSP frequency significantly higher than wild-type values.
Reported values are mean ± SEM. n = 16, 12, 10, 10 and 8 for wild-type, brp5.38, brp1.3, brp5.45 and brp69 NMJs, respectively. One-way ANOVA p < 1.1×10−7. Asterisk marks pairwise significance from post-hoc comparison with Bonferroni criterion (* p < 0.01).
