Pitch coding shifts between place and entracking mechanisms depending on stimulus level

Evidence

An obvious limitation in this scalar code is the upper limit of firing (usually near ~ 500 Hz). We surmise that at low SPLs and fundamental frequencies > 500 Hz, a spectral or place mechanism codes for pitch (Cedolin and Delgutte 2005 ; Larsen et al. 2008 ). With increasing SPL the place code degrades but entracking improves and first occurs in the neurons with the lowest thresholds for the spectral components present. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4521
