Thus it appears that amplification in the cochlea resides in the gating of the outer hair cell cflia, while the motility is due to passive piezoelectric properties of the cell wall. The flow through the gate has significant nonlinearity at small amplitudes of displacement of the cilia (10 nm). Sufficiently high amplitudes of displacement of the cilia will cause the tip links to buckle. We estimate that this will occur at around 70 dB sound pressure level, thereby turning off the active process for higher sound intensity. [Pg.1072]

Distortion product otoacoustic emissions (DPOAEs) can be used to evaluate the function of the outer hair cells alone. DPOAEs are created as a by-product of outer hair cell motility following a specific stimulus presentation. When the basilar membrane moves in response to a sound, outer hair cells are stimulated and by electromotility aid in tuning specific frequencies to stimulate the inner hair cells... [Pg.281]

Microscopic Characteristics Cylindrical (bacilli) and spherical (cocci) forms characterize this genus. Cells are extremely variable in shape, measuring 0.4-0.5 x 1.0-1.7 microns. Typically the bacterial cell has one or more flagella ("motile hairs") at one or both of its poles. (Bacillus has flagella along its entire outer periphery). Both organisms use these flagella for locomotion. Species in... [Pg.252]
