Fig. 2 — Developmental changes in passive membrane properties of barrelette and interbarrelette cells. A: scatter plot of resting membrane potentials against postnatal ages for the 2 types of cells. ●, barrelette cells. ○, interbarrelette cells. B: averaged resting potentials at different ages for barrelette cells ( ) and interbarrelette cells (□). Bar: mean value. Error bar: SE. Number in parentheses: tested cell number. Note that there are no developmental changes in resting potentials (P > 0.05) for both cell types and no difference (P > 0.05) between the 2 types at all age groups. C: scatter plot of input resistances of the 2 types of cells suggests a decrease in input resistances with age. D: input resistances in both barrelette and interbarrelette cells are significantly smaller at postnatal days (PND) 7–13 than those at PND 1–3 (P < 0.02, **). Because the input resistance of interbarrelette cells declines faster than that of barrelette cells, the input resistance of the 2 types is significantly different (P < 0.02, ##) at PND 4–6 and PND 7–13.
