Vestibular signals carried by pathways subserving plasticity of the vestibulo-ocular reflex in monkeys.
The vestibulo-ocular reflex (VOR) is subject to long-term adaptive changes that minimize retinal image slip and keep eye movement equal to and opposite head movement. As a step toward identifying the site of neural changes, we have used a transient vestibular stimulus to study the dynamic response properties of the vestibular signals carried by the modifiable pathways. In normal monkeys, "rapid...
متن کاملPhysiological properties of vestibular primary afferents that mediate motor learning and normal performance of the vestibulo-ocular reflex in monkeys.
We have used electrical stimulation of the vestibular apparatus to reveal parallels between the physiological responses of the vestibular afferents activated at different currents and the properties of the evoked eye movements before and after magnifying spectacles had been used to cause motor learning in the vestibulo-ocular reflex (VOR). Stimulation with the lowest currents caused little or n...
متن کاملEffects of vestibulo-ocular reflex exercises on vestibular compensation after vestibular schwannoma surgery.
OBJECTIVE To assess vestibular function in a large group of vestibular schwannoma patients so that we could determine whether simple vestibular exercises speed vestibular dysfunction recovery after tumor removal surgery. STUDY DESIGN A prospective investigation of the vestibular dysfunction experienced by patients in the first 12 weeks after surgery. SETTING Vestibular investigation unit at...
متن کاملArtificial Balance: Restoration of the Vestibulo-Ocular Reflex in Humans with a Prototype Vestibular Neuroprosthesis
The vestibular system plays a crucial role in the multisensory control of balance. When vestibular function is lost, essential tasks such as postural control, gaze stabilization, and spatial orientation are limited and the quality of life of patients is significantly impaired. Currently, there is no effective treatment for bilateral vestibular deficits. Research efforts both in animals and huma...
متن کاملVestibular-nerve inputs to the vestibulo-ocular reflex: a functional-ablation study in the squirrel monkey.
Advantage was taken of differences in the electrical excitability of vestibular-nerve fibers to characterize the afferent input to the canal-related vestibulo-ocular reflex. Large anodal (inhibitory) currents, when delivered to both ears, result in a selective, reversible ablation of irregular afferents. Their background discharge and responses to head rotations are temporarily abolished. The s...
