Basic Property of Yawing Sensation in Visual-vestibular Interaction

Visual - vestibular Interaction : Basic Science to Clinical Relevance

Introduction The vestibular system, which provides a signal of head motion to the brain, mediates functions of gaze and postural stabilisation via vestibular-ocular (VOR) and vestibular-spinal reflexes. The vestibular system is also key in generating sensations of selfmotion and spatial orientation required for navigation in the environment. The vestibular system influences these reflex and per...

Visual–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...

Clinical 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....
