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

The Automated Vestibular Rehabilitation System: Normative Data From a Machine Vision-Guided Platform. [PDF]

Laryngoscope
The Automated Vestibular Rehabilitation System (AVRS) is a machine vision‐based tool designed to increase accessibility to vestibular rehabilitation therapy by automating exercise delivery and tracking head‐eye movements in real time. In n = 40 healthy adults, the AVRS accurately measured vestibulo‐ocular reflex (VOR) gain values near physiologic norms

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

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 ...

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.

Floccular Syndrome-An Atypical Presentation of Paraneoplastic Cerebellar Degeneration (PCD) [PDF]

Liaquat National Journal of Cancer Care, 2023
The flocculus, a small and distinct region of the cerebellum, plays a crucial role in coordinating eye movements, especially in stabilizing visual images on the retina during head movements.
