Octopus cells fire one spike per click up to 700 clicks per second
Evidence
In AN fibers, firing rate also shows some dependence on click train frequency, but much weaker than in octopus cells. We have also observed entracking to sinusoidally amplitude modulated (SAM) tones. … Similar to entracking to pure tones mentioned in the previous section, firing rate increased linearly with modulation frequency; was similar for the different SPLs tested; and declined steeply once an upper limit is reached. The CF of the neuron was 2.4 kHz, but the response to pure tones at CF was much lower than to low-frequency tones delivered in the tail of the tuning curve, to which the neuron entracked — Dijk, Pim van, Physiology, Psychoacoustics and…, 4494
