Values are means ± SD; n is the number of cells; > significantly greater with P ≤ 0.005; ≫ significantly greater with P ≤ 0.001; –not significantly different. Statistically significant differences were determined using the Mann–Whitney U test. Electrophysiological parameters were measured as described in methods.
