Tuning the cochlea: wave-mediated positive feedback between cells

Bell, James Andrew

Description

Frequency analysis by the mammalian cochlea is traditionally thought to occur via a hydrodynamically coupled 'travelling wave' along the basilar membrane. A persistent difficulty with this picture is how sharp tuning can emerge. This paper proposes, and models, a supplementary or alternative mechanism: it supposes that the cochlea analyses sound by setting up standing waves between parallel rows of outer hair cells. In this scheme, multiple cells mutually interact through positive feedback of...[Show more]
