"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

Effect of adaptive plasticity of linear vestibulo-ocular reflex upon angular vestibulo-ocular reflex

Auris Nasus Larynx, 2000
The 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, 2006
The 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, 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

Simulations and Sensitivity Analysis of the Vestibulo-Ocular Reflex

IEEE Transactions on Biomedical Engineering, 1987
Computer 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

Science
Vertebrates 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.

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 ...

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.

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.
