The CaMKII inhibitor KN-93 reduces IMI voltage dependence. Proctolin-induced IMI at different concentrations of KN-93. For statistical analysis, KN-93 was grouped into a low-dose (2-5 μm) and a high-dose (10-20 μm) group, in addition to a control group (0 μm). A, Representative I–V curves for a KN-93 experiment. B, Averaged I–V curves for all KN-93 experiments. C, Quantification of data shown in B. A one-way repeated-measures ANOVA showed that KN-93 significantly increased proctolin-induced IMI slope (F(2,5) = 46.239, p = 5.96 × 10−4w). Recordings are from LP neurons.
