Inner hair cells only convert oscillations to spike rates in the model
Evidence
The inner haircells play a secondary role in the model. Indeed, the inputs to the inner haircells are the outputs of the model: preprocessing in this context ends at the oscillation-tospike-rate transformation. Finally, all sections of the model along the basilar membrane are assumed to have the same basic structure. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing.
