All data are presented and graphed as means ± SEM. The Steel-Dwass test was used to assess the relative diameters of cells, input resistances, and Ca2+ velocities, all variables for which normality of the data could not be assumed. For other electrophysiological data, either Student’s t-test for two groups, or two-way ANOVA with Bonferroni post hoc t-tests, were used. For behavioral data, Student’s t test or two-way repeated measures ANOVA with Bonferroni post hoc test were used. Normality of the data was assessed by the Shapiro-Wilk test. P values <0.05 were considered significant.
