WebThe analysis occurs because the cochlea is a tuned structure, different parts of which vibrate in response to different frequencies; the transduction because the hair cells of Corti's organ are capable of changing minute amounts of mechanical energy into an electrochemical form that stimulates the endings of the nerve fibres. WebHair cells—sensory cells sitting on top of the basilar membrane—ride the wave. As the hair cells move up and down, microscopic hair-like projections (known as stereocilia) that perch on top of the hair cells bump against an overlying structure and bend. Bending causes pore-like channels, which are at the tips of the stereocilia, to open up.
