| | Vestibulo-ocular reflex - definition of Vestibulo-ocular reflex in Encyclopedia |
 | | The vestibulo-ocular reflex, or VOR, is a reflex eye movement that stabilizes images on the retina during head movement by producing an eye movement in the direction opposite to head movement. | | | For the VOR, the vestibular nuclei serve the role that the deep cerebellar nuclei serve for other cerebellum-dependent behaviors like eyeblink conditioning. | | | Such adjustments are needed throughout life, as neurons and muscles develop, weaken, and die--or for humans, when a new pair of eyeglasses changes the magnification of the visual field. |

| | Similarly, the vestibulo-ocular reflex is accurate during natural turns in that the reflexive eye velocity compensates for the head velocity and stabilizes vision relative to Earth-fixed targets. | | | The vestibulo-ocular reflex influences vision during natural movement much more than is generally appreciated, and it is capable of subtle and occasional profound influence on vision in aviation. | | | The vestibulo-ocular reflex automatically stabilizes the eyes relative to external visual surroundings during head movements to maintain visual acuity for Earth-fixed targets. |

| | The classic example of the vestibuloocular reflex (VOR) and its functional significance was described by a physician with peripheral vestibular dysfunction. | | | VOR disturbances are treated with different forms of rehabilitation exercises. | | | Thus, the main purpose of the VOR is to maintain objects on the fovea, thereby allowing a person to clearly visualize objects during brief head movements. |

| | The object of this study was to determine what aspects of the vestibulo-ocular reflex are affected by temperature changes naturally experienced by a poikilothermic animal, the goldfish. | | | However, individual physiological, biochemical, and/or pharmacological thermolabile processes that underlie the operation of this reflex could alter the operation of this reflex in a poikilotherm. | | | 2) Experiments were conducted on the visuo-vestibulo- (Vis-VOR) and vestibulo- ocular reflex (VOR) during normal operation and during the acquisition (learning) and retention (memory) phases of adaptive gain change. |
