Journal of Neuroscience, 2017 The mechanisms orchestrating transient and sustained exocytosis in auditory inner hair cells (IHCs) remain largely unknown. These exocytotic responses are believed to mobilize sequentially a readily releasable pool of vesicles (RRP) underneath the ...

Compartmentalized and signal-selective gap junctional coupling in the hearing cochlea [PDF]
, 2006 Gap junctional intercellular communication (GJIC) plays a major role in cochlear function. Recent evidence suggests that connexin 26 (Cx26) and Cx30 are the major constituent proteins of cochlear gap junction channels, possibly in a unique heteromeric ...

A Biophysical Model of the Inner Hair Cell: The Contribution of Potassium Currents to Peripheral Auditory Compression [PDF]
Journal of the Association for Research in Otolaryngology, 2006 The term peripheral auditory compression refers to the fact that the whole range of audible sound pressure levels is mapped into a narrower range of auditory nerve responses. Peripheral compression is the by-product of independent compressive processes occurring at the level of the basilar membrane, the inner hair cell (IHC), and the auditory nerve ...

Rat Auditory Inner Hair Cell Mechanotransduction and Stereociliary Membrane Diffusivity Are Similarly Modulated by Calcium [PDF]
iScience, 2020 The lipid bilayer plays a pivotal role in force transmission to many mechanically-gated channels. We developed the technology to monitor membrane diffusivity in order to test the hypothesis positing that Ca2+ regulates open probability (P o) of cochlear hair cell mechanotransduction (MET) channels via the plasma membrane. The stereociliary membrane was

eLife, 2019 The mammalian auditory sensory epithelium has one of the most stereotyped cellular patterns known in vertebrates. Mechano-sensory hair cells are arranged in precise rows, with one row of inner and three rows of outer hair cells spanning the length of the

Retardation of cochlear maturation and impaired hair cell function caused by deletion of all known thyroid hormone receptors [PDF]
, 2001 The deafness caused by early onset hypothyroidism indicates that thyroid hormone is essential for the development of hearing. We investigated the underlying roles of the TRa1 and TRß thyroid hormone receptors in the auditory system using receptor ...

Calcium entry into stereocilia drives adaptation of the mechanoelectrical transducer current of mammalian cochlear hair cells [PDF]
, 2014 Mechanotransduction in the auditory and vestibular systems depends on mechanosensitive ion channels in the stereociliary bundles that project from the apical surface of the sensory hair cells.

Perspectives on Auditory Neuropathy: Disorders of Inner Hair Cell, Auditory Nerve, and Their Synapse [PDF]
, 2008 The term auditory neuropathy (Starr, A. et al., 1996) was first used to describe a hearing disorder due to altered function of the auditory nerve in the presence of preserved functions of cochlear outer hair cells (OHCs; Starr, A. et al., 1991). The hearing loss has specific features reflecting impairment of auditory temporal processes that are ...

Inner-Hair Cells Parameterized-Hardware Implementation for Personalized Auditory Nerve Stimulation [PDF]
, 2011 In this paper the hardware implementation of an inner hair cell model is presented. Main features of the design are the use of Meddis’ transduction structure and the methodology for Design with Reusability. Which allows future migration to new hardware and design refinements for speech processing and custom-made hearing ...

Static length changes of cochlear outer hair cells can tune low-frequency hearing.
PLoS Computational Biology, 2018 The cochlea not only transduces sound-induced vibration into neural spikes, it also amplifies weak sound to boost its detection. Actuators of this active process are sensory outer hair cells in the organ of Corti, whereas the inner hair cells transduce ...
