The functional operation of the vestibulo-ocular reflex
2022The biophysical properties of the labyrinthine semicircular canals, and the electrophysiological properties of peripheral vestibular afferent neurons over a range of stimulus frequencies, are reviewed. Resting discharge activity and adaptive properties of vestibular neurons are discussed.

Effects of halothane on the vestibulo-ocular reflex
American Journal of Otolaryngology, 1980The differential effect of halothane on the characteristics of fast and slow components of vestibular nystagmus was investigated in rabbits. Eye movements were monitored using the "magnetic search coil" method and evaluated with the aid of a laboratory minicomputer. Low concentrations of halothane act preferentially on the fast component.

Basic framework of the vestibulo-ocular reflex
2022Direct 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 ...

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 ...

"Velocity leakage" in the pigeon vestibulo-ocular reflex
Biological Cybernetics, 1994The 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

Effect of adaptive plasticity of linear vestibulo-ocular reflex upon angular vestibulo-ocular reflex
Auris Nasus Larynx, 2000The vestibulo-ocular reflex (VOR) produces compensatory eye movements during head movements. The VOR consists of the angular VOR and the linear VOR. The VOR is under adaptive control that corrects VOR performance when visual-vestibular mismatch arises during head movements. Most experiments concerning plasticity of the VOR have used the angular VOR. So

Effect of aluminum consumption on the vestibulo-ocular reflex
Metabolic Brain Disease, 2006The effects of chronic exposure (90 days) to Aluminum chloride (AlCl(3)) were analyzed in 3, 10 and 24 month old male rats (n=270) by investigating the function of the VOR (vestibulo-ocular reflex) in correlation with Aluminum (Al) concentrations in blood and brain.

The Vestibulo-Ocular Reflex in Newborn Rats
Acta Oto-Laryngologica, 1979To 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

Simulations and Sensitivity Analysis of the Vestibulo-Ocular Reflex
IEEE Transactions on Biomedical Engineering, 1987Computer simulations and sensitivity analysis of vestibulo-ocular reflex (VOR) gain and phase were performed. The analyses were used to identify neural structures and anatomic sites capable of producing abnormal VOR gain and phase behaviors reported to exist in blind adults.

Sensation is Dispensable for the Maturation of the Vestibulo-ocular Reflex
ScienceVertebrates stabilize gaze using a neural circuit that transforms sensed instability into compensatory counter-rotation of the eyes. Sensory feedback tunes this vestibulo-ocular reflex throughout life. Gaze stabilization matures progressively, either due to similar tuning, or to a slowly developing circuit component.
