Auditory nerve fibers maintain stimulus phase but vary absolute spike timing

Evidence

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. Individual spike timing varied, consistent with phase locking (Anderson et al. 1970 ; Sachs et al. 1974 ; Joris et al. 1994 ; Köppl 1997 ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 2848
