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.

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.

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 ...
