Changes in input resistance, access resistance, and time course of decay do not account for the late reduction in DDI. (A) Mean input resistance (MΩ) vs. age shows no change between P15 and P30 that would account for the reduction in DDI. N = 11 cells for P3, P6, P9, and P30; N = 12 for P12, P15, and P20. (B) Access resistance is slightly positively correlated with the extent of DDI and does not account for the reduction. Mean DDI (arbitrary units) evoked in physiological magnesium and 1 μM TTX plotted vs. access resistance in MΩ for 24 cells ages P3–P30. Correlation coefficient = 0.10. (C) Average decay time constants τ for DDI (in physiological magnesium). Time constants are not significantly different with age (ANOVA p = 0.37). N = 4 cells for P3, P12 and P30; N = 3 for P6, P9, P15, and P20.
