Values are ± SE with range in parentheses. One-way ANOVA followed by Tukey's multiple comparison test: * statistically significant difference vs. 1st AP on the LTS (P < 0.01); † statistically significant difference vs. AP induced by depolarizing step (P < 0.001); ‡ statistically significant difference vs. 2nd AP on LTS (P < 0.05).
