Normal hearing depends on sound amplification within the mammalian cochlea. The amplification, without which the auditory system is effectively deaf, can be traced to the correct functioning of a group of motile sensory hair cells, the outer hair cells of the cochlea. Acting like motor cells, outer hair cells produce forces that are driven by graded changes in membrane potential. The forces depend on the presence of a motor protein in the lateral membrane of the cells. This protein, known as… Expand

TLDR
The extended frequency range of the mammalian cochlea has probably co-evolved with a novel hair cell type, the outer hair cell and its constituent membrane protein, prestin. Expand
Prestin and Motility of the Cochlear Outer Hair Cell
TLDR
This paper deals with the recent studies identifying the relationship between prestin and electromotility, the recent findings of the structure and function of prestin, and the recent prestin-related topics. Expand

TLDR
Although the tertiary structure of prestin has yet to be determined, results from the presence of its homologs in nonmammalian species suggest a possible conformation in mammalian OHCs, how it can act like a transport protein, and how it may have evolved. Expand
Cold Spring Harbour ‘Hearing and deafness’ Outer hair cells and electromotility Short title: Cochlear Outer Hair Cells
Outer hair cells (OHCs) of the mammalian cochlea behave like actuators: they feed energy into the cochlear partition and determine the overall mechanics of hearing. They do this by generatingExpand
Cochlear hair cells: The sound‐sensing machines
TLDR
The role of both afferent and efferent synapse in the inner ear is reviewed and the role of nicotinic receptor, assembled by α9α10 subunits, participates in this synapse. Expand
Ion flow in cochlear hair cells and the regulation of hearing sensitivity
TLDR
How ion transport proteins in the hair cells of the mammalian cochlea work to produce a sensitive but stable hearing organ and the relative insensitivity of cochlear gain to short-term changes in the endocochlear potential is discussed. Expand
Active outer hair cell motility can suppress vibrations in the organ of Corti
TLDR
The results show that the interactions could be either constructive or destructive, which implies that the outer hair cells can either amplify or suppress vibrations in the organ of Corti, suggesting that the cochlear actuators can both amplify and suppress vibrations to enhance co chlear tuning.

Integrating the active process of hair cells with cochlear function

TLDR
The auditory system is enhanced by an active process in cochlear hair cells that amplifies acoustic signals several hundred-fold, sharpens frequency selectivity and broadens the ear's dynamic range. Expand
Effects of cochlear loading on the motility of active outer hair cells
TLDR
The results suggest that somatic motility evolved to enhance a preexisting amplifier based on active hair-bundle motility, thus allowing mammals to hear high-frequency sounds. Expand
The Spatial Pattern of Cochlear Amplification
TLDR
It is shown that cochlear amplification produces negative damping that counters the viscous drag impeding traveling waves; targeted photoinactivation locally interrupts this compensation. Expand

TLDR
It is shown here that outer hair cells selectively take up fructose, at rates high enough to suggest that a sugar transporter may be part of the motor complex. Expand

TLDR
It is suggested, that outer hair cells might amplify sound-induced oscillations in the inner ear and thus increase sensitivity and frequency selectivity of hearing. Expand
Prestin is the motor protein of cochlear outer hair cells

It is concluded that prestin is the motor protein of the cochlear outer hair cell, which is specifically expressed in outer hair cells that express prestin. Expand
Motility-associated hair-bundle motion in mammalian outer hair cells
TLDR
The OHCs showed bundle movement with peak responses of up to 830 nm, which suggests that the bundle movement originated in somatic motility and that somatic Motility has a central role in cochlear amplification in mammals. Expand

The mechanism underlying the shape changes induced by different stimuli are discussed, and the role of fast and slow motility in the physiology and pathology of auditory transduction is assessed. Expand

TLDR
It is shown that the cylindrical outer hair cells change their axial stiffness as their membrane potential is altered and this change is accompanied by mechanical reactance changes of the cells. Expand

In the inner ear, sensory hair cells not only detect but also amplify the softest sounds, allowing us to hear over an extraordinarily wide intensity range, giving rise to exquisite frequency discrimination. Expand

TLDR
It is shown here that mechanically induced hair-bundle deflection produces somatic motility of the cell, indicating that the cell may possess capabilities to affect its mechanical environment under control of its own receptor potential and, thereby, participate in a local cochlear feedback process.

Evidence for active hair bundle motion and its connection to MT channel adaptation is summarized and key factors for the hair bundle motor to play a role in the mammalian cochlea include the size and speed of force production. Expand
Prestin is required for electromotility of the outer hair cell and for the cochlear amplifier
TLDR
It is shown that targeted deletion of prestin in mice results in loss of outer hair cell electromotility in vitro and a 40–60 dB loss of cochlear sensitivity in vivo, without disruption of mechano-electrical transduction in outer hair cells. Expand
