Fig. 2. I~V curve and difference of number of spikes in single-, pair-exposed rats and naïve rats. (A) Left, Voltage responses to a depolarizing or hyperpolarizing pulse about 50, 100 and 200 pA to estimate electrophysiological properties (Top) and the representative sample of pyramidal neuron and interneuron pattern (Bottom). Right, I~V curve in pyramidal neuron and interneuron showed different slope. (B) There was a significant difference between the number of AP spikes in the pyramidal neurons of naïve rats and pair-exposed rats at 100 and 200 pA current injection (Pair vs. Naïve, Bonferroni post-hoc test, *p<0.05), whereas the number of AP spikes in the interneurons was increased in single- and pair-exposed rats compared to naïve rats at 200 pA current injection (Pair vs. Naïve, ****p<0.0001; Single vs. Naïve, ####p<0.0001; Bonferroni post-hoc test).
