Visually enhanced vestibulo‐ocular reflex gain in patients with vestibular disease
Laryngoscope Investigative Otolaryngology, 2023 Objective Vestibular migraine (VM) is a diagnostic challenge. Visually enhanced vestibulo‐ocular reflex (VVOR) gain, a measure of the visual–vestibular interaction, has been proposed as a tool for diagnosing VM.

Vestibulo-Ocular Reflex Is Modulated by Noisy Galvanic Vestibular Stimulation
Frontiers in Neurology, 2022 We investigated whether noisy galvanic vestibular stimulation (nGVS) modulates the vestibulo-ocular reflex (VOR) and whether this effect is correlated with the effect of nGVS on body sway. Thirty healthy young adults participated.

Head shaking does not alter vestibulo ocular reflex gain in vestibular migraine
Frontiers in Neurology, 2022 Vestibular Migraine (VM) is the most common cause of non-positional episodic vestibular symptoms. Patients with VM commonly report increased motion sensitivity, suggesting that vestibular responses to head movement may identify changes specific to VM ...

The cat's vestibulo‐ocular reflex.
The Journal of Physiology, 1980 1. The conscious cat's vestibulo‐ocular reflex (v.o.r.) has been studied using the electro‐oculogram to measure eye movements. A servomotor was used to rotate the head horizontally while the body remained stationary. 2. The frequency content of natural head movements in the cat has been determined by Fourier analysis.

Image motion with color contrast suffices to elicit an optokinetic reflex in Xenopus laevis tadpoles
Scientific Reports, 2021 The optokinetic reflex is a closed-loop gaze-stabilizing ocular motor reaction that minimizes residual retinal image slip during vestibulo-ocular reflexes.

Ontogeny of murine bony semicircular canal form
The Anatomical Record, EarlyView.Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...

Functional Dissociation Between Cervical VEMP and Posterior Canal vHIT in 1770 Unselected Ears
The Laryngoscope, EarlyView.Cervical VEMP and posterior canal vHIT are conventionally treated as measures of a single inferior vestibular unit. In 1770 unselected ears from a diagnosis‐agnostic registry, the two tests disagreed in 72.7% of ears abnormal on at least one test, with chance‐corrected agreement near zero (κ = 0.097) and unchanged across age strata.
