Effects of apamin on spiking responses to step current injections. (A) Spiking responses to step current injections before (aCSF) and during apamin perfusion. Apamin had a smaller effect in the SHS group at a given injected current (A1), total number of spikes (A2), and membrane voltage (A3). (B) mAHP amplitude before and during apamin perfusion. Apamin had a smaller effect in the SHS group at same injected current (B1) and membrane voltage (B3) but not at same total discharge rate (B2). (C) mAHP area before and during apamin perfusion. As in the case of mAHP amplitude, apamin had a smaller effect in the SHS group at same injected current (C1) and membrane voltage (C3) but not at same total discharge rate (C2). (D) Three-way repeated measures ANOVA results. *p < 0.05 SHS vs. FA, p < 0.05 apamin vs. aCSF, §p < 0.05 exposure x apamin interaction.
