Studies of the vestibulo-ocular reflex on STS 4, 5 and 6 [PDF]

open access: yes, 1988
The vestibulo-ocular reflex (VOR) may be altered by weightlessness. Since this reflex plays a large role in visual stabilization, it was important to document any changes caused by space flight. This is a report on findings on STS-4 through 6 and is part

Floccular fossa size is not a reliable proxy of ecology and behaviour in vertebrates

open access: yesScientific Reports, 2017
The cerebellar floccular and parafloccular lobes are housed in fossae of the periotic region of the skull of different vertebrates. Experimental evidence indicates that the lobes integrate visual and vestibular information and control the vestibulo ...

Vestibular function in degenerative parkinsonism

open access: yesFrontiers in Neurology
IntroductionThe degenerative pathology in Parkinson’s disease (PD), multisystem atrophy (MSA) and progressive supranuclear palsy (PSP) have different spatial distribution in the brainstem. Our aim was find out in what way this pathology affects brainstem

The evaluation of adaptation of the vestibulo-ocular reflex in patients after vestibular schwannoma surgery

open access: yes, 2018
This thesis deals with the evaluation of the vestibulo-ocular reflex in patients indicated for neurosurgical resection of vestibular schwannoma, executed at the Motol University Hospital.

A Dynamical Model of Context Dependencies for the Vestibulo-Ocular Reflex

open access: yes, 1996
The vestibulo-ocular reflex (VOR) stabilizes images on the retina during rapid head motions. The gain of the VOR, i.e. the ratio of eye to head rotation velocity, measured with the eyes focused at a distance is typically around-1.

Walsh & Hoyt: Vestibulo-Ocular System

open access: yes, 2005
During normal behavior, it is natural to use a combination of eye and head movements, whether to voluntarily acquire or track a target of interest or to reflexively stabilize gaze in response to a passive body movement.

Initial and Sinusoidal Vestibulo-Ocular Reflex Following Focal Brainstem Lesions

open access: yes, 1996
Most head movements made under natural viewing conditions are of high frequency. In order to preserve clear vision during head motion, the vestibulo-ocular reflex (VOR) must produce compensatory smooth eye movements with a short latency and the ratio of ...

The Vestibulo-Ocular Reflex in Chiari Type II Malformation

open access: yes, 2006
Chiari type II malformation (CII) is a congenital anomaly of the cerebellum and brainstem, both important structures for processing the vestibulo-ocular reflex (VOR). Little information is available on the VOR in CII.
