* P < 0.0001 compared with control (unpaired 2-tailed Student's t-test).
† P < 0.002 compared with control (paired 2-tailed Student's t-test).
‡ Time constant was estimated using a single exponential fit of the charging current.
§ P < 0.001 compared with control (paired 2-tailed Student's t-test).
¶ Capacitance was determined by dividing time constant by input resistance.
