The effects of removing - and Ca²⁺-channels on resonance at different resting membrane potentials for equivalent RLC circuit model. (a) The voltage responses at the hyperpolarized resting membrane potential (−80 mV) for control condition (upper trace) and without -channel (lower trace). (b) The impedance magnitude at the hyperpolarized resting membrane potential (−80 mV) for control condition (solid line) and without -channel (dashed line). (c) At the depolarized resting membrane potential (−53 mV), the voltage response for control condition (upper trace) and without -channel (lower trace). (d) The impedance magnitude at the depolarized resting membrane potential (−80 mV) for control condition (solid line) and without -channel (dashed line). For removing Ca²⁺-channel, at hyperpolarized resting membrane potential (−80 mV), (e) the voltage response for control condition (upper trace) and without Ca²⁺-channel (lower trace) and (f) impedance magnitude for control condition (solid line) and without -channel (circles). At depolarized resting membrane potential (−53 mV), (g) the voltage response for control condition (upper trace) and without Ca²⁺-channel (lower trace), and (h) impedance magnitude for control condition (solid line) and without Ca²⁺-channel (dashed line).
