Realistic Basilar Membrane Tuning Does Not Require Active Processes

摘要: This paper describes two versions of a cochlear model (called the OHCAP model), both which exhibit mechanical response tuning very similar to that recently measured in real cochlea. Two assumptions made formulation model, make it different from previous models, are basilar membrane has radial modes vibration (corresponding division into its arcuate and pectinate zones), outer hair cells (OHCs) greatly modify mechanics zone. The presented here have models for OHCs. Both realistic tuning, so remains be determined is more acceptable terms physiological justifiability. However, passive, shows active processes not necessary explain cochlea’s sharp tuning.
