Motor learning can improve both the accuracy and precision of motor performance. We analyzed changes in the average trajectory and the variability of smooth eye movements during motor learning in rhesus monkeys. Training with a compound visual-vestibular stimulus could reduce the variability of the eye movement responses without altering the average responses. This improvement of eye movement p...

A sudden unilateral loss or impairment of vestibular function causes vertigo, dizziness and impaired postural function. In most occasions, everyday activities supported or not by vestibular rehabilitation programs will promote compensation and the symptoms subside. As the compensatory process requires sensory input, matching performed motor activity, both motor learning of exercises and matchin...

Sensing gravity is vital for our perception of spatial orientation, the control of upright posture, and generation of our everyday activities. When an astronaut transitions to microgravity or returns to earth, the vestibular input arising from self-motion will not match the brain's expectation. Our recent neurophysiological studies have provided insight into how the nervous system rapidly reorg...

various dimensions of the human vestibular aqueduct were evaluated in two groups, patient and control, and these measurements were compared. both groups were examined clinically, followed by audiometric evaluation and temporal bone high resolution ct scan. it was found that in approximately one third of the patient group (with idiopathic snhl), the vestibular aqueduct was 1.5 mm or larger. also...

background and aim: motion sickness (ms) is usually generated when there is a mismatch between the senses which serve balance. one of these senses is related to vestibular system, so it is highly possible that ms reflects in vestibular test results. but there are some conflicts in correlation between vestibular findings and ms. thus, the objective of this study was to provide an overview of ves...

background and aim: vestibular migraine is a type of migraine that causes vertigo, dizziness, and imbalance in addition to typical migraine symptoms. in this study, we aimed to investigate vestibular system in these patients by videonystagmography (vng), electrocochleography (ecochg), and vestibular evoked myogenic potential (vemp) testing. methods: this empirical study was conducted on 10 pati...

Human postural control is regulated by the vestibular, somatosensory, and visual systems. These types of sensory information are integrated in central nervous system to ascertain body’s position space. Proper functioning senses necessary for body maintain equilibrium. Bilateral vestibulopathy (BVP) a condition which bilateral peripheral vestibular function reduced. Its treatment includes rehabi...
