The cochlear amplifier is a positive feedback mechanism within the cochlea that provides acute sensitivity in the mammalian auditory system. [1] The main component of the cochlear amplifier is the outer hair cell (OHC) which increases the amplitude and frequency selectivity of sound vibrations using electromechanical feedback.
The Greenwood function correlates the position of the hair cells in the inner ear to the frequencies that stimulate their corresponding auditory neurons.Empirically derived in 1961 by Donald D. Greenwood, the relationship has shown to be constant throughout mammalian species when scaled to the appropriate cochlear spiral lengths and audible frequency ranges.
The cochlea is the part of the inner ... in response to the vibrations coming from the ... distance from the oval window depending upon the soundwave frequency.
The summating potential (SP), first described by Tasaki et al. in 1954, represents the direct current (DC) response of the hair cells as they move in conjunction with the basilar membrane, [6] as well as the DC response from dendritic and axonal potentials of the auditory nerve. [7] The SP is the stimulus-related potential of the cochlea.
Cochlear nerve fibers (30,000+) each have a most sensitive frequency and respond over a wide range of levels. [ 17 ] [ 18 ] Simplified, nerve fibers' signals are transported by bushy cells to the binaural areas in the olivary complex , while signal peaks and valleys are noted by stellate cells, and signal timing is extracted by octopus cells.
Outputs of simulated cochlear filters centred at 364, 1498 and 4803 Hz (from bottom to top) in response to a segment of a speech signal, the sound “en” in “sense”. These filter outputs are similar to the waveforms that would be observed at places on the basilar membrane tuned to 364, 1498 and 4803 Hz.
[6] [7] They originally believed that the potential originated from the cochlear nerve, but it was later discovered that the response is non-neural and is cochlear in origin, specifically from the outer hair cells. [8] [9] This phenomenon came to be known as the cochlear microphonic (CM). The FFR may have been accidentally discovered back in ...
Stacked ABR is the sum of the synchronous neural activity generated from five frequency regions across the cochlea in response to click stimulation and high-pass pink noise masking. [9] This technique was based on the 8th cranial nerve compound action potential work of Teas, Eldredge, and Davis in 1962. [10]
