  • Values are means ± SE; n values are in parentheses. Leakage current is the current applied to keep the membrane potential at −80 mV in voltage-clamp mode; pipette resistance is the resistance of the patch pipettes used; serial resistance is the resistance consisting of membrane resistance and pipette resistance.
