(number) after ‘Age’: the number of marmoset used; (number) after values: the number of cells tested. Abbreviations: PD, postnatal day; Rin, input resistance; RMP, resting membrane potential; τ, membrane time constant. 1The number of action potentials generated in response to a 500 ms current step at an intensity corresponding to rheobase +40 pA. *P < 0.05, **P < 0.01, ***P < 0.001 vs. corresponding PD0 & 1 values (Tukey's multiple comparison test after one-way ANOVA). ††P < 0.01, †††P < 0.001 vs. a corresponding 2 week value (Tukey's multiple comparison test after one-way ANOVA).
