Turning semicircular canal function on its head: dinosaurs and a novel vestibular analysis. [PDF]

PLoS ONE, 2013
Previous investigations have correlated vestibular function to locomotion in vertebrates by scaling semicircular duct radius of curvature to body mass. However, this method fails to discriminate bipedal from quadrupedal non-avian dinosaurs.

Speech Perception in Ménière Disease

International Archives of Otorhinolaryngology, 2023
Introduction Ménière disease (MD) affects the inner ear, comprising the cochlea and semicircular canals. Symptoms include severe incapacitating vertigo, nausea, vomit, aural fullness, and sensorineural hearing loss – in which speech ...

HSV-1 not only in human vestibular ganglia but also in the vestibular labyrinth [PDF]

, 2001
Reactivation of herpes simplex virus type 1 (HSV-1) in the vestibular ganglion (VG) is the suspected cause of vestibular neuritis (VN). Recent studies reported the presence of HSV-1 DNA not only in human VGs but also in vestibular nuclei, a finding that ...

Management of Lateral Semicircular Canal Benign Paroxysmal Positional Vertigo

Frontiers in Neurology, 2020
Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral vestibular vertigo. It is caused by free-floating otoconia moving freely in one of the semicircular canals (canalolithiasis) or by otoliths adhered to the cupula ...

The Human Semicircular Canals Orientation Is More Similar to the Bonobos than to the Chimpanzees

PLoS ONE, 2014
For some traits, the human genome is more closely related to either the bonobo or the chimpanzee genome than they are to each other. Therefore, it becomes crucial to understand whether and how morphostructural differences between humans, chimpanzees and ...

Importance of Vestibulo-ocular Reflex Gain and Refixation Saccade Analysis in Individuals with Auditory Neuropathy Spectrum Disorder

International Archives of Otorhinolaryngology, 2020
Introduction Auditory neuropathy spectrum disorder (ANSD) features the presence of otoacoustic emissions, poor speech identification score and absent auditory brainstem response.

Benign Paroxysmal Positional Vertigo with Simultaneous Involvement of Multiple Semicircular Canals

Korean Journal of Audiology, 2014
Background and Objectives Benign paroxysmal positional vertigo (BPPV) generally involves a single semicircular canal (single canal BPPV) but it has been reported that more than one semicircular canal on either the same or the opposite side can be ...

The variability of inner ear orientation in saurischian dinosaurs: testing the use of semicircular canals as a reference system for comparative anatomy

PeerJ, 2013
The vestibular system of the inner ear houses three semicircular canals—oriented on three nearly-orthogonal planes—that respond to angular acceleration stimuli.

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

Advanced 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.
