Auditory nerve spike peaks repeat at intervals set by the neuron’s best frequency

Evidence

Intracellular recordings from NM axons in NL supported the hypothesis that oscillatory neurophonic click responses were composed of many NM click responses. Averaging intracellular click recordings from NM afferents revealed two to five PSTH peaks (Fig. 2a ). PSTH peaks were separated in time by intervals equal to the inverse of the neuron’s best frequency (BF), a 2π phase interval. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2858
