Current concepts of the vestibular system reviewed: 2. Visual/vestibular interaction and spatial orientation.
The vestibular system contributes to the generation of conjugate eye movements, spatial orientation, and postural control. The functional connections of the vestibular end-organs and of the descending vestibulospinal pathways and their importance to postural control were reviewed in the previous paper by Keshner and Cohen (pp. 320-330). This paper reviews the ascending vestibular pathways, the ...
متن کاملVisual-vestibular interaction with telescopic spectacles.
Vestibularly and visually driven eye movements interact to compensate for head movements to maintain the necessary retinal image stability for clear vision. The wearing of highly magnifying telescopic spectacles requires that such compensatory visual-vestibular interaction operate in a quantitative regime much more demanding than that normally encountered. We employed electro-oculography to inv...
متن کاملVisual–vestibular interaction in progressive supranuclear palsy
We measured the stability of gaze during horizontal head rotations at 1-3 Hz in four patients with progressive supranuclear palsy (PSP), while they viewed a stationary target. Median gain of compensatory eye movements was 0.94, similar to control subjects. During rotation in darkness, median gain of vestibulo-ocular reflex (VOR) was 0.88, similar to controls. Conversely, the median gain of smoo...
متن کاملClinical signs of visual-vestibular interaction.
Visual suppression of vestibulo-ocular reflexes (induced vestibular nystagmus) differs between normal subjects and patients with various neurological disorders. Abnormalities of VOR suppression were associated consistently with abnormalities of the visual and/or vesitibular oculomotor reflexes and in particular with abnormal smooth pursuit eye movements in the direction of abnormal suppression....
متن کاملVestibular, proprioceptive, and haptic contributions to spatial orientation.
The control and perception of body orientation and motion are subserved by multiple sensory and motor mechanisms ranging from relatively simple, peripheral mechanisms to complex ones involving the highest levels of cognitive function and sensory-motor integration. Vestibular contributions to body orientation and to spatial localization of auditory and visual stimuli have long been recognized. T...
