Voltage-gated conductances can counteract filtering effect of membrane capacitance (Heras et al '16)


Phenomenological inductance generated by voltage-gated ionic conductances (Na or K) can increase the gain bandwidth product of subthreshold signaling (e.g. psps) in a neuron, reducing the attenuation and slowing caused by membrane capacitance.
