Pipettes (borosilicate glass; 2–3 MΩ resistance) were filled with solution containing (mM): K-gluconate 125, KCl 20, NaCl 10, amphotericin-B 0.44, HEPES 10; pH 7.2 (adjusted with KOH). Cell membrane capacitance (Cm) was determined by dividing the time constant of the decay of the ...
Hyperpolarization-activated cyclic nucleotide–gated (HCN) channels are expressed as four different isoforms (HCN1-4) in the heart and in the central and peripheral nervous systems. In the voltage range of activation, HCN channels carry an inward current mediated by Na+and K+, termed Ifin the ...
