The Mechanics of the Growing Semicircular Canal [PDF]

open access: yesJournal of Experimental Biology, 1973
ABSTRACT The motion of the endolymph in the semicircular canal is described with the aid of a linear second-order system, comprising the applied angular acceleration and the linear displacement, the linear velocity and the linear acceleration of the endolymph.

Benign paroxysmal positional vertigo: a multi-center study

open access: yesThe Egyptian Journal of Otolaryngology, 2022
Background Benign paroxysmal positional vertigo (BPPV) is the most frequent vestibular disorder with significant morbidity, psychosocial impact, and medical costs.

Design and analysis of HSC-BPPV diagnostic maneuver based on virtual simulation

open access: yesFrontiers in Neurology, 2023
BackgroundThe preferred supine roll test for the diagnosis of horizontal semicircular canal BPPV has several disadvantages, including difficulty in locating the affected ear, inconsistent nystagmus performance on repeated testing, and lack of a typical ...

Technique of Multi-Planar CT Image Reconstruction for the Evaluation of Superior Semicircular Canal Dehiscence Syndrome

open access: yesPhilippine Journal of Otolaryngology Head and Neck Surgery, 2011
Superior semicircular canal dehiscence (SSCD) syndrome is an unusual cause of vertigo that was first identified by Minor in 1998. The patients initially described by Minor presented with vertigo, oscillopsia, and/or dysequilibrium related to sound ...

Semicircular canals in Anolis lizards: ecomorphological convergence and ecomorph affinities of fossil species [PDF]

open access: yesRoyal Society Open Science, 2017
Anolis lizards are a model system for the study of adaptive radiation and convergent evolution. Greater Antillean anoles have repeatedly evolved six similar forms or ecomorphs: crown-giant, grass-bush, twig, trunk, trunk-crown and trunk-ground.

LRRC8A Regulates Outer Hair Cell Volume and Electromotility and is Required for Hearing

open access: yesAdvanced Science, EarlyView.
This study identifies LRRC8A‐dependent volume‐regulated anion channels (VRACs) as essential for cochlear outer hair cells' electromotility and auditory signal amplification. LRRC8A deficiency disrupts cell volume control, impairs auditory sensitivity, and causes deafness, while targeted LRRC8A re‐expression restores auditory function.

Semicircular Canal Influences on the Developmental Tuning of the Translational Vestibulo-Ocular Reflex

open access: yesFrontiers in Neurology, 2018
Vestibulo-ocular reflexes (VORs) rely on neuronal computations that transform vestibular sensory signals into spatio-temporally appropriate extraocular motor commands.

Auditory Hair Cell Mechanotransduction Channels Dynamically Shape the Mechanical Properties of Their Membrane Environment

open access: yesAdvanced Science, EarlyView.
This work shows, for the first time, that the stereocilia membrane in cochlear hair cells is dynamically regulated by the mechanotransduction channel to impact the membrane mechanical properties. This work provides direct evidence that the opening and closing associated with the MET channel is regulating the membrane viscosity suggesting that the MET ...

Comparative Cochlear Transcriptomics in Echolocating Bats and Mouse Reveals Hras as Protector Against Noise‐Induced Hearing Loss

open access: yesAdvanced Science, EarlyView.
Comparative cochlear transcriptomics of noise‐exposed bats (Miniopterus fuliginosus) and mice reveals bat‐specific protection mechanisms for noise‐induced hearing loss (NIHL), identifying Hras as a key hub regulator. Functional studies in mice show hair‐cell‐specific Hras overexpression significantly reduced hair‐cell damage and NIHL by activating the ...

The use of videonystagmography head impulse test (VHIT) in the diagnostics of semicircular canal injuries in patients with vertigo

open access: yesInternational Journal of Occupational Medicine and Environmental Health, 2014
Objectives: The aim of the study was to assess the function of semicircular canal in videonystagmography head impulse test (VHIT) in the patients with vertigo and balance disorders.
