How do caloric tests relate to vestibular function and stereocilia?

May 10, 2021 ... We show that IHC and OHC stereocilia are similarly TM-embedded and that Ca 2+ ducts connect the TM to the stereocilia of IHCs and OHCs. Male Smpx null mice showed a progressive hearing loss starting from high frequency at the 3rd month. Hearing loss in female mice was milder and occurred later. These results provide the first direct evidence that type I hair cells have significantly more stereocilia than type II hair cells. For the latter option to work without downtime, each stereocilium (or sets of mechanically-connected stereocilia) must be able to execute the recovery by itself ... You are studying the mechanism by which stereocilia in inner ear hair cells bend and transduce a ... staining reveals that it is located at the base of ... Abstract. Stereocilia are actin-based protrusions on auditory and vestibular sensory cells that are required for hearing and balance. They convert physical ... ... stereocilia bathing in the surrounding endolymph. The cell body itself is localised in the perilymph compartment (see transverse section of the organ of ... Aug 23, 2016 ... Abstract. Stereocilia are actin-based protrusions on auditory and vestibular sensory cells that are required for hearing and balance. They ... Deflection of the bundle of stereocilia is mechanically responsible for stretching ion pores in the stereocilia, allowing a cation current to pass into the cell ... Jul 22, 2024 ... We conclude that stereocilia fusion is linked with the failure to maintain cellular proteostasis and with disturbances in stereociliary calcium balance.
