Cross-neuron firing-rate uniformity distinguishes pitch codes from unrelated low activity

Evidence

One may wonder what distinguishes the low firing rate of an entracking neuron to a low frequency component vs. the low firing rate to a component above the entracking limit. The key would again be in the uniform firing rate, with low variability, across neurons in the case of a low frequency component. Above the entracking limit, firing rate is no longer clamped to the value dictated by the dominant ISI of a neuron’s inputs and will vary across neurons. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4494 (#corroborates, via linked claim)
