Effects of the KCC2 blocker VU0463271 on recurrent IEDs at DIV5–DIV7. A, C, Extracellular field potential recordings in the CA1 pyramidal cell layer in the organotypic hippocampal slices at DIV6 before (control), during and after application of 0.1 μm (A) and 1 μm (C) VU0463271 for 10 min. Expansion of IEDs in control and in the presence of VU0463271. B, D, Corresponding summary plots of the frequency and mean duration of recurrent IEDs in individual cultures (open symbols) and corresponding power of electrical activity in 5-min windows. Filled symbols indicate group mean ± SD. VU0463271 (1 μm) significantly increased the mean frequency, duration, and power of epileptiform discharges (n/s corresponds to p > 0.05; *p < 0.05; **p < 0.01; ***p < 0.001, one-way RM ANOVA, Tukey’s test).
