Recovery of vestibulo-ocular reflex in vestibular neuronitis depending on severity of vestibulo-ocular reflex damage

Vestnik otorinolaringologii, 2019
The aim of this study is to evaluate clinical symptoms and recovery of vestibule-ocular reflex (VOR) in patients with vestibular neuronitis (VN) in dependence on severity of VOR damage according to video head impulse test (vHIT).45 patients with VN and superior or both superior and inferior vestibular nerves involvement were recruited and horizontal ...

Fluctuating Vestibulo-Ocular Reflex in Ménière's Disease

Otology & Neurotology, 2017
Objectives: To describe the fluctuating high velocity vestibular ocular-reflex (VOR) during the Ménière's attacks and correlate those features with pathophysiology. Patients: A patient with unilateral Ménière's disease (MD) was evaluated closely during and after acute vertigo ...

Identification of the vestibulo-ocular reflex dynamics

2014 36th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2014
The vestibulo-ocular reflex (VOR) plays an important role in our daily activities by enabling us to fixate on objects during head movements. Modeling and identification of the VOR improves our insight into the system behavior and helps in diagnosing various disorders.

Abnormal vestibulo-ocular reflex

2015
Abstract This is a chapter on Abnormal vestibulo-ocular reflex from the Eyes/Eye Movements section of A Manual of Neurological Signs. Most of the chapters contain a description of the sign, associated signs, and cases, supported by clinical videos and figures.

Vestibulo-ocular reflex

Current Opinion in Neurology, 1995
Recent animal and clinical studies on the vestibulo-ocular reflex deal with a number of physiological and clinical aspects from which three were chosen for this review: (1) the torsional vestibulo-ocular reflex and its disorders; (2) the otolith contribution to the vestibulo-ocular reflex; and (3) neurotransmitters, neuropharmacological aspects, and ...

Human vestibulo-ocular reflex adaptation is frequency-selective.

Journal of Neurophysiology, 2019
The vestibulo-ocular reflex (VOR) is the only system that maintains stable vision during rapid head rotations. The VOR gain (eye/head velocity) can be trained to increase using a vestibular-visual mismatch stimulus.

The Chinchilla's Vestibulo-ocular Reflex

Acta Oto-Laryngologica, 1989
The horizontal vestibulo-ocular reflex (VOR) was measured and characterized in seven adult chinchillas using 0.01 to 1.0 Hz angular velocity sinusoids. Gains were less than compensatory, and were variable from day to day but phases were highly repeatable both within and between animals.

Unifying vestibulo-ocular reflexes

2001 Conference Proceedings of the 23rd Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005
We present an eye/head gaze controller based on recent findings in biological gaze control. Despite the absence of an explicit VOR mechanism the model is able to (i) produce classical VOR responses and (ii) reject head perturbations during the saccadic portion of a gaze shift executed to a remembered target - what is usually attributed to a separate ...

Relationship between motion sickness susceptibility and vestibulo-ocular reflex gain and phase

Journal of Vestibular Research-Equilibrium & Orientation, 2018
BACKGROUND: It has been proposed that individual susceptibility to motion sickness is related to the vestibulo-ocular reflex (VOR) through the activation of the velocity storage mechanism.

Assessment of Vestibulo-ocular Reflex Gain and Catch-up Saccades During Vestibular Rehabilitation.

Otology and Neurotology, 2018
OBJECTIVE To assess, in patients referred to vestibular rehabilitation (VR) for persistence of disability after acute unilateral vestibulopathy (AUV), whether the video head impulse test (vHIT) can be a useful technique to define the efficacy of the ...
