The vestibular system processes information about head movement and orientation. No unimodal vestibular cortex has been identified in the mammalian brain. Rather, vestibular inputs are combined with many other sensory signals in the cortex. This arrangement suggests that vestibular input could influence processing in other sensory modalities. Here we show that vestibular stimulation differentia...

Many authors have reported different useful studies in evaluating vestibular function through vestibular, somatosensory, and visuocortical systems using the test of balance and in assessing vestibular function through the vestibulospinal system using craniocorpography. We researched 100 patients suffering from tinnitus and vertigo (36 men and 64 women). Diagnoses of vestibular dysfunction can b...

Maintaining a multi-jointed inverted pendulum in vertical position is an extremely challenging engineering problem. However, most healthy individuals not only can stand upright with ease, they can maintain stability during motion and under some perturbations. Many studies have shown that postural control involves very complicated interactions between many subsystems – i.e. sensory, neural, moto...

Introduction: Bilateral vestibular dysfunction (BVD) is an uncommon finding in vestibular assessment, and the combination of BVD and orthopedic problems represents a rare and challenging case for treatment.   Case Report: The patient had several previous back surgeries and received gentamycin after surgery. After 6 months, she experienced continuous dizziness, unsteadiness and oscillopsia. ...

The human vestibular organ transmits sensory information to various components of the central nervous system related to head movement and, obviously, among these components, to its terminal region(s) in the vestibular parts of the cerebral cortex. Study of vestibular structures dates back to historical epochs when primitive considerations on cerebral global function were made without knowledge ...

INTRODUCTION Galvanic vestibular stimulation (GVS) is able to evoke distinct responses in the muscles used for balance. These reflexes, termed the short (SL) and medium latency (ML) responses, can be altered by sensory input; decreasing in size when additional sensory cues are available. Although much is known about these responses, the origin and role of the responses are still not fully under...

The vestibular system sub-serves a number of reflex and perceptual functions, comprising the peripheral apparatus, the vestibular nerve, the brainstem and cerebellar processing circuits, the thalamic relays, and the vestibular cerebral cortical network. This system provides signals of self-motion, important for gaze and postural control, and signals of traveled distance, for spatial orientation...

The mouse has become an important model system for studying the cellular basis of learning and coding of heading by the vestibular system. Here we recorded from single neurons in the vestibular nuclei to understand how vestibular pathways encode self-motion under natural conditions, during which proprioceptive and motor-related signals as well as vestibular inputs provide feedback about an anim...

To answer Alsmith’s questions about the existence of a vestibular sense, we outline in the first part of our reply why we believe the vestibular sense is a true “sixth sense”. We argue that vestibular information constitutes distinct sensory events and that absolute coding of body orientation and motion in the gravitycentered space is the important unique feature of the vestibular system. In th...

PURPOSE The vestibular system is the part of the inner ear responsible for balance. Vertigo and dizziness are generally caused by vestibular disorders and are very common symptoms in people over 60 years old. One of the most efficient treatments at the moment is vestibular rehabilitation, permitting to improve the symptoms. However, this rehabilitation therapy is a highly empirical process, whi...
