WebMar 31, 1995 · Outer hair cells undergo somatic elongation-contraction cycles in vitro when electrically stimulated. This "electromotile" response is assumed to underlie the high sensitivity and frequency selectivity of amplification in the mammalian cochlea. This process, presumably operating on a cycle-by-cycle basis at the frequency of the stimulus, is ...

WebOct 13, 2024 · INTRODUCTION. The sensitivity of the mammalian inner ear is extraordinary. At the threshold of hearing, the incoming sound produces vibrations inside the organ of Corti that are of the same order of magnitude or less than the thermal noise motion (Hudspeth, 1989, 1997; Dallos, 1996).Such sensitivity is achieved through an energy …
WebHearing sensitivity in mammals is enhanced by more than 40 dB (that is, 100-fold) by mechanical amplification thought to be generated by one class of cochlear sensory cells, the outer hair cells. In addition to the mechano-electrical transduction required for auditory sensation, mammalian outer hair cells also perform electromechanical transduction, …
