The absolute and relative volume of major sensory and integrative brain regions of the southern bluefin tuna Thunnus maccoyii are examined using magnetic resonance imaging (MRI). A dominant cerebellum projects into the midbrain ventricular space, while the optic tectum represents a smaller proportion of total brain volume than previously estimated ...

Midline Head Tap to Image the Human Vestibular Cortex on fMRI
A simple head tap can stimulate inner ear otolith organ activation. In this pilot proof‐of‐concept study, midline forehead taps were delivered in the magnetic resonance imaging (MRI) scanner to elicit an observable response in the areas most suspected of representing a vestibular cortex.

Abstract figure legend Recent work has shown transcranial electrical stimulation of the dorsolateral prefrontal cortex (dlPFC) to mitigate vestibular perceptions. Though definitive pathways require further elucidation, this interaction may be modulated by dlPFC inhibitory action on vestibular signalling in the insular cortex, thalamus and/or the ...

Balance disequilibrium is a significant contributor to falls in the elderly. The most common cause of balance dysfunction is loss of sensory cells from the vestibular sensory epithelia of the inner ear.

Low-frequency sinusoidal linear acceleration (0.08 Hz, ±4 mG) modulates skin sympathetic nerve activity (SSNA) in seated subjects (head vertical), suggesting that activation of the utricle in the peripheral vestibular labyrinth modulates SSNA. The aim of

ABSTRACT Sudden sensorineural hearing loss (SSNHL) is most often idiopathic or related to benign conditions such as Meniere's disease. However, SSNHL caused by vertebrobasilar ischemia is rare and may precede life‐threatening neurological deficits.

Expression of Sox21 during chicken inner ear development.
(A) Sox21 mRNA showed faint levels of expression at E3 in the otic vesicle. (B) Upregulation of Sox21 expression was observed in the presumptive posterior crista and the presumptive superior crista regions at E5. (C) At E7 Sox21 transcripts were detected

TMC function, dysfunction, and restoration in mouse vestibular organs
Tmc1 and Tmc2 are essential pore-forming subunits of mechanosensory transduction channels localized to the tips of stereovilli in auditory and vestibular hair cells of the inner ear.

The study investigates the shape of the semicircular canals in the inner ear of three sister mole species—Talpa europaea, Talpa aquitania, and Talpa occidentalis—using geometric morphometrics on 58 specimens. It finds both interspecific and intraspecific variability in canal morphology, but no evidence of sexual dimorphism.

High‐Resolution Visualization of the Human Semicircular Canals Using Optical Coherence Tomography
ABSTRACT The semicircular canals are essential sensors of the vestibular organ. Current clinical in vivo imaging techniques lack the resolution needed to visualize critical vestibular microstructures, such as the membranous labyrinth and crista ampullaris.
