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 ...

Vestibulo-ocular reflex pathways in internuclear ophthalmoplegia

Annals of Neurology, 1999
We measured the vestibulo-ocular reflex (VOR) during head impulses in a patient with right-sided internuclear ophthalmoplegia. Head impulses are rapid, passive, high-acceleration, low-amplitude head rotations in the direction of a particular semicircular canal (SCC). Adduction of the right eye was abnormally slow during right lateral SCC head impulses.

Vestibulo-ocular reflex and visual vestibulo-ocular reflex during sinusoidal rotation in children.

Acta oto-laryngologica. Supplementum, 1997
To clarify the relationship between vestibular and visual (optokinetic) stimuli in normal children, we investigated the vestibulo-ocular reflex (VOR) and visual VOR (VVOR). The subjects were 20 healthy children aged 3-6 years and 24 healthy adults aged 21-29 years.

Basic framework of the vestibulo-ocular reflex

2022
Direct and indirect pathways mediating the vestibulo-ocular reflexes, considering contributions made by the vestibular commissure, cerebellum, and vestibular efferent neurons are reviewed. This background leads to a detailed treatment of three-dimensional aspects of the vestibulo-ocular reflex, comparing the planes of the labyrinthine semicircular ...

"Velocity leakage" in the pigeon vestibulo-ocular reflex

Biological Cybernetics, 1994
The transfer characteristics of the vestibulo-ocular reflex (VOR), and of the semicircular canal primary afferents (SCPAs) that drive it, have been studied in several species. In monkeys and cats, the dominant time constant describing horizontal VOR dynamics (tau hv) is longer than that (tau c) of horizontal SCPAs. This lengthening of the time constant

The Vestibulo-Ocular Reflex in Newborn Rats

Acta Oto-Laryngologica, 1979
To study the development of vestibular functioning, the vestibulo-ocular reflex was tested in rats of increasing age. High frequency electrical stimulation of the vestibular nerve elicited characteristic conjugate eye movements in newborn rats well before the eyes were open (about day 15 after birth) and before the semi-circular canals had reached full

Cerebellar learning in the vestibulo–ocular reflex

Trends in Cognitive Sciences, 1998
The vestibulo-ocular reflex, because of its close relationship with the cerebellum and its marked adaptiveness, has become a model system for studying the functions of the cerebellum. It has been hypothesized that an evolutionarily old part of the cerebellum, the flocculus, forms a modifiable accessory pathway for the vestibulo-ocular reflex arc for ...

[Functional vestibulo-ocular reflex test].

Lin chuang er bi yan hou tou jing wai ke za zhi = Journal of clinical otorhinolaryngology head and neck surgery, 2019
Summary In recent years, the diagnosis and treatment of vertigo and balance disorders have become a hot topic of multidisciplinary attention. The evaluation method of vestibular function has also been improved, providing important evidence for the diagnosis and differential diagnosis of vertigo related diseases.

The Vestibulo-Ocular Reflex Arc

1974
Three topics related to Vestibulo-Ocular Reflexes will be considered in this chapter: (1) The function of eye movements induced by the Vestibulo-Ocular Reflex Arc. (2) The pattern of eye movements induced by various parts of the vestibular apparatus.

Modelling brain function: the vestibulo-ocular reflex

Current Opinion in Neurology, 2001
Function and dysfunction of the brain cannot be completely understood on the molecular level alone. A second level is required, namely that of system analysis and mathematical modelling. It is obvious that the problems of sensorimotor control of biological systems are related to the control of technical systems.
