Diode pump cochlear audition theory.
A model of the cochlea is developed whereby the motion of the basilar membrane due to sound pressure in the scala media creates, through the pivotal motion of the pillars of Corti, modulated pressure on the fluid in the inner sulcus. This modulated pressure causes fluid to flow through the tectorial gap at selected longitudinal positions along the basilar membrane causing excitation or inhibition of the hair cell activity depending upon the direction of fluid flow. Specific functional relationships are developed for a two component model composed of a resonant and a nonresonant region. Relevant experimental data show good agreement with the predictions of the model.
