Encoding the auditory spectrum: lateral inhibition

This idea attempted to resolve a fundamental uncertainty in early auditory processing: Is the acoustic spectrum encoded by the pattern of average activation across the tonotopic axis (place code), or by the temporal response patterns it evokes in each auditory-nerve fiber (temporal code)? It explained how specific spatiotemporal response features inherent to cochlear function could encode the acoustic spectrum in the response patterns of the auditory nerve. It also demonstrated how such a code harmoniously combines spatial and temporal cues, how it maintains a faithful spectral representation despite the limited dynamic range of the auditory-nerve, and how it can be readily decoded to extract the acoustic spectrum by plausible lateral inhibitory interactions in the recipient cochlear nucleus.
