Perceived Vertical and Lateropulsion: Clinical Syndromes, Localization, and Prognosis [PDF]

open access: yes, 2000
We present a clinical classification of central vestibular syndromes according to the three major planes of action of the vestibulo-ocular reflex: yaw, roll, and pitch.

The cat's vestibulo‐ocular reflex.

open access: yesThe Journal of Physiology, 1980
1. The conscious cat's vestibulo‐ocular reflex (v.o.r.) has been studied using the electro‐oculogram to measure eye movements. A servomotor was used to rotate the head horizontally while the body remained stationary. 2. The frequency content of natural head movements in the cat has been determined by Fourier analysis.

Comorbidity Patterns Between Hearing Loss and Symptomatic Dizziness in Middle‐Aged and Older Adults

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective To explore the comorbidity patterns between hearing loss and symptomatic dizziness (HL‐SD) in middle‐aged and older adults. Methods This cross‐sectional study used data from the 1999 to 2004 National Health and Nutrition Examination Survey (NHANES). After excluding incomplete data, 2961 participants aged 40–69 were analyzed. Logistic

Vestibulo-ocular reflex and the head impulse test

open access: yesArquivos de Neuro-Psiquiatria, 2012
The authors highlights the importance of the vestibulo-ocular reflex examination through the head impulse test as a diagnostic method for vestibular dysfunction as well as, and primarily, a bedside semiotic resource capable of differentiating between ...

Video ocular counter roll: A bedside test of otolith‐ocular function

open access: yesAnnals of Clinical and Translational Neurology, 2023
Here we review the clinical value of a video‐oculography test for clinical evaluation of vestibular otolith function. This test is known as the video ocular counter roll (vOCR) and is based on measurement of torsional vestibulo‐ocular reflex with a ...

Three-dimensional vestibular eye and head reflexes of the chameleon: characteristics of gain and phase and effects of eye position on orientation of ocular rotation axes during stimulation in yaw direction [PDF]

open access: yes, 2018
We investigated gaze-stabilizing reflexes in the chameleon using the three-dimensional search-coil technique. Animals were rotated sinusoidally around an earth-vertical axis under head-fixed and head-free conditions, in the dark and in the light.

The Neuroanatomical Correlates of Training-Related Perceptuo-Reflex Uncoupling in Dancers [PDF]

open access: yes, 2013
Sensory input evokes low-order reflexes and higher-order perceptual responses. Vestibular stimulation elicits vestibular-ocular reflex (VOR) and self-motion perception (e.g., vertigo) whose response durations are normally equal.

Recompression Improves Release Success in Pollack (Pollachius pollachius): A Step Towards Assessing Post Release Mortality in a Recreational Fishery

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT The recreational fishery for pollack (Pollachius pollachius) in the northeast Atlantic is impacted by the species' high sensitivity to barotrauma. When captured at depth and brought to the surface, gas expansion within the peritoneal cavity can cause a variety of injuries and hinder release.

Hybrid Model of the Context Dependent Vestibulo-Ocular Reflex: Implications for Vergence-Version Interactions

open access: yesFrontiers in Computational Neuroscience, 2015
The vestibulo-ocular reflex (VOR) is an involuntary eye movement evoked by head movements. It is also influenced by viewing distance. This paper presents a hybrid nonlinear bilateral model for the horizontal angular vestibulo-ocular reflex (AVOR) in the ...

Central adaptation to repeated galvanic vestibular stimulation: implications for pre-flight astronaut training. [PDF]

open access: yesPLoS ONE, 2014
Healthy subjects (N = 10) were exposed to 10-min cumulative pseudorandom bilateral bipolar Galvanic vestibular stimulation (GVS) on a weekly basis for 12 weeks (120 min total exposure).
