Consequences of Converting Graded to Action Potentials upon Neural Information Coding and Energy Efficiency
Figure 4
The information rates of the spiking neuron model are robust to voltage-gated ion channel noise.
A. The firing rates of the spiking neuron model (stochastic voltage-gated Na+ and K+ channels), a modified model with stochastic voltage-gated Na+ and deterministic voltage-gated K+ channels and a modified model with deterministic voltage-gated Na+ and stochastic voltage-gated K+ channels evoked by low mean, high standard deviation or high mean, low standard deviation input stimuli. B. The total entropy, C. The noise entropy, and D. The mutual information rates of the same models shown in A evoked by the same stimuli.
