The Importance of the Hook Region of the Cochlea for Bone-Conduction Hearing |pdf=|usr=}}{{24988357}} gab.com Text The Importance of the Hook Region of the Cochlea for Bone-Conduction Hearing JO: Biophys J http://www.kidney.de/pget.php?&tw=1&pmid=24988357 #FOAvip For the most part, the coiled shape of the cochlea has been shown to have only minor importance for air-conducted hearing. It is hypothesized, however, that this coiled shape may play a more significant role for the bone-conducted (BC) route of hearing, through inertial forces exerted by the middle ear and cochlear fluid, and that this can be tested by comparing the results of applying BC stimuli in a variety of different directions. A three-dimensional finite element model of a human middle ear coupled to the inner ear was formulated. BC excitations were simulated by applying rigid-body vibrations normal to the surface of the basilar membrane (BM) at 0.8 (d1), 5.8 (d2), 15.6 (d3), and 33.1 (d4) mm from the base of the cochlea, such that relative motions of the fluid within the cochlea produced excitations of the BM. The vibrational direction normal to the BM surface at the base of the cochlea (d1) produced the highest BM velocity response across all tested frequencies?higher than an excitation direction normal to the BM surface at the nonbasal locations (d2?d4), even when the stimulus frequency matched the best frequency for each location. The basal part of the human cochlea features a well-developed hook region, colocated with the cochlear vestibule, that features the largest difference in fluid volume between the scala vestibuli (SV) and scala tympani (ST) found in the cochlea. The proximity of the hook region to the oval and round windows, combined with it having the biggest fluid-volume difference between the SV and ST, is thought to result in a maximization of the pressure difference between the SV and ST for BC stimuli normal to the BM in this region, and consequently a maximization of the resulting BM velocity.
