Input resistance (Input R) and capacitance (Capa) were measured with a −5 mV pulse from a holding potential of −70 mV. The action potential (AP) amplitude and duration were measured during a 10 ms depolarizing pulse and the sag resulting from activation of Ih was measured during a 1 s hyperpolarization from −70 to −100 mV.
