Manual head rotation synchronised to a metronome is a feasible and valid method for assessing visually enhanced vestibulo-ocular reflexes and vestibulo-ocular reflex suppression [PDF]

Frontiers in Neurology
IntroductionThe visually enhanced vestibulo-ocular reflex (VVOR) and vestibulo-ocular reflex suppression (VOR-S) are critical in evaluating vestibular and cerebellar contributions to oculomotor control. This study aimed to investigate the feasibility and

Visually enhanced vestibulo‐ocular reflex gain in patients with vestibular disease [PDF]

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 Suppression: Clinical Relevance and Assessment in the Digital Age [PDF]

Digital Biomarkers
Background: Visual acuity and image stability are crucial for daily activities, particularly during head motion. The vestibulo-ocular reflex (VOR) and its suppression (VORS) support stable fixation of objects of interest.

The vestibular implant: effects of stimulation parameters on the electrically-evoked vestibulo-ocular reflex [PDF]

Frontiers in Neurology
IntroductionThe vestibular implant is a neuroprosthesis which offers a potential treatment approach for patients suffering from vestibulopathy. Investigating the influence of electrical stimulation parameters is essential to improve the vestibular ...

A New Suppression Index Calculation Using the Visually Enhanced Vestibulo-Ocular Reflex and Vestibulo-Ocular Reflex Suppression Paradigms in the Video Head Impulse Test [PDF]

Audiology Research
The aim of this study is to calculate the gains of the quantified visually enhanced vestibulo-ocular reflex (qVVOR) and the quantified vestibulo-ocular reflex suppression (qVORS), using a specific system to generate a visual suppression index (SI) in ...

Head shaking does not alter vestibulo ocular reflex gain in vestibular migraine [PDF]

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 ...

Evaluation of the vestibulo-ocular reflex in head-tilt mutant mice [PDF]

Biochemistry and Biophysics Reports
The vestibulo-ocular reflex (VOR) is an involuntary reflex essential for maintaining clear vision and balance during head movement. It stabilizes gaze by generating compensatory eye movements in the opposite direction to head movement, ensuring that the ...

Professional baseball players demonstrate superior dynamic visual acuity and differences in vestibulo-ocular reflex performance, compared to similarly aged healthy controls [PDF]

BMC Sports Science, Medicine and Rehabilitation
Background Baseball-specific movement paradigms require heightened ocular performance driven by the vestibular system. Normative data of vestibulo-ocular measures for high-level athlete populations is limited in the current literature, particularly under

Emerging and distinct video head impulse test responses in elderly with vestibular symptoms

Brazilian Journal of Otorhinolaryngology, 2022
Introduction: Dizziness has been reported to be the most common symptom in elderly population. Video head impulse test, VHIT, allows clinicians to assess the vestibular function in elderly individuals, during their initial stages of vestibular symptoms ...

Convergent innervations of mesencephalic trigeminal and vestibular nuclei neurons onto oculomotor and pre-oculomotor neurons—Tract tracing and triple labeling in rats

PLoS ONE, 2022
In studies of vestibulo-ocular reflex (VOR), the horizontal VOR circuit is much clearer than vertical-torsional VOR. The circuit and mechanism of gravity-related vertical-torsional VOR is probably weak.
