Hyperventilation-Induced Nystagmus in Acute Unilateral Vestibulopathy: A Correlation with Vestibulo-ocular Reflex Gain and Clinical Implication

BACKGROUND: Hyperventilation-induced nystagmus test (HINT) is capable of generating a response in 77.2% of cases of acute unilateral vestibulopathy (AUVP); both nystagmus toward the affected side (excitatory pattern) and toward the healthy side ...

Asymmetries in the vertical vestibulo-collic reflex

, 1990
The results support the hypothesis that vestibulo-ocular reflez and vestibulo-collic reflex share a common circuitry having an intrinsic asymmetry aimed at counterbalancing the gravity load during upward head displacements.

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

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 ...

Vestibular neuritis: Vertigo and the high-acceleration vestibulo-ocular reflex [PDF]

, 2008
Patients after vestibular neuritis (VN) often report persistent dizziness and disequilibrium. We correlated persistent symptoms with sustained impairment of the high-acceleration horizontal vestibulo-ocular reflex as determined by quantitative searchcoil

Evaluation of Vestibulo-Ocular Reflex (VOR) in Tinnitus Patients with Normal Hearing

, 2021
OBJECTIVES: This study aimed to evaluate the correlation between tinnitus parameters (duration, severity, reaction, handicap levels) and vestibule-ocular reflex (VOR) gain values in patients with tinnitus with normal hearing without vertigo or any other ...

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

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 ...

Parametric influence of otoliths on Vestibulo-Ocular Reflex (VOR)

, 1989
Anticompensatory fast phases (AFPs) can be modified in amplitude. direction and symmetry by the macular input regardless of the macular effect on the vestibulo-ocular reflex.

Expression of a Protein Kinase C Inhibitor in Purkinje Cells Blocks Cerebellar LTD and Adaptation of the Vestibulo-Ocular Reflex [PDF]

, 1998
Cerebellar long-term depression (LTD) is a model system for neuronal information storage that has an absolute requirement for activation of protein kinase C (PKC). It has been claimed to underlie several forms of cerebellar motor learning.
