Organization and Control of the Vestibulo-Ocular Reflex

1979
Publisher Summary Two generations of vestibulo-ocular reflex (VOR) models can be distinguished. This chapter describes a first generation model of VOR. The first generation models describe the VOR as an isolated system with uncontrollable characteristics.

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 ...

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 ...

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

Signal processing in the vestibulo-ocular reflex

2022
In this chapter, Robinson develops models to account for the neural control of the vestibulo-ocular reflex in response to horizontal and vertical head rotations. By combining knowledge of the discharge properties of the several subpopulations of neurons that contribute to vestibular eye movements with their known anatomical connections, these models ...

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

The functional operation of the vestibulo-ocular reflex

2022
The 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.

Plasticity and repair of the vestibulo-ocular reflex

2022
It is self-evident, once one thinks about it, that the vestibulo-ocular reflex must have caretaker systems that keep it operating correctly over the span of a lifetime. When a movement is not correct (e.g., in position, speed, direction) it is said to be dysmetric. For the vestibulo-ocular reflex (VOR), if eye velocity is not equal and opposite to head

"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
