Overview: Hearing loss, tinnitus, hyperacusis, and the role of central gain

LE Roberts, R Salvi - Neuroscience, 2019 - Elsevier
Sensory hair cells in the cochlea transduce environmental sounds into driven high-fidelity
neural signals that are conveyed by auditory nerve fibers to structures in the central auditory …

[HTML][HTML] Inner hair cell loss disrupts hearing and cochlear function leading to sensory deprivation and enhanced central auditory gain

R Salvi, W Sun, D Ding, GD Chen… - Frontiers in …, 2017 - frontiersin.org
There are three times as many outer hair cells (OHC) as inner hair cells (IHC), yet IHC
transmit virtually all acoustic information to the brain as they synapse with 90–95% of type I …

[HTML][HTML] Tinnitus: does gain explain?

W Sedley - Neuroscience, 2019 - Elsevier
Many, or most, tinnitus models rely on increased central gain in the auditory pathway as all

Pump up the volume: could excessive neural gain explain tinnitus and hyperacusis?

H Brotherton, CJ Plack, M Maslin, R Schaette… - Audiology and …, 2015 - karger.com
Naturally occurring stimuli can vary over several orders of magnitude and may exceed the

Loudness modulation after transient and permanent hearing loss: implications for tinnitus and hyperacusis

P Fournier, M Schönwiesner, S Hébert - Neuroscience, 2014 - Elsevier
Loudness is the primary perceptual correlate of sound intensity. The relationship between
sound intensity and loudness is not fixed, and can be modified by short-term sound …
