Sensitivity of firing rate in single-compartment neurons depends on induction electric field

This paper establishes a new neuron model in the effect of induction electric field (IEF) based on the Hodgkin-Huxley (HH) model to investigate how a single-compartment neuron encodes the stimulus and how the sensitivity of firing rate to input fluctuations changes under different IEF. Then add noisy direct current IEF (DCIEF) and alternating current IEF (ACIEF) to the neuron model respectively at the bifurcation point. By the data obtained and our analysis, this paper shows how the variance of IEF frequency or amplitude influences the neuronal sensitivity of firing rate.
