  1. Pearson's regression analysis was used to ensure that the parameters used to characterize the cells did not depend on the amplitude of the injected current. To ensure that the parameters were not influenced by the elapsed time during the whole-cell recordings, they were compared at the beginning and at the end of the recording period with either parametric (paired t-test) or nonparametric (Sign-test) tests as appropriate (following Shapiro–Wilk's normality test, at P < 0.01). Despite P-values > 0.01, the full width at half maximum of the last AP, the decay times at 25%, 50% and 75% of AHP of the last AP and last ISI were not included in our analysis, as they were not included for the first AP either.
