In a previous study, we observed spontaneous restoration of vestibular function in young adult rodents following excitotoxic injury of the neuronal connections within vestibular endorgans. The functional restoration was supported by a repair of synaptic contacts between hair cells and primary vestibular neurons. This process was observed in 2/3 of the animals studied and occurred within 5 days ...

The electronystagmographical analysis of the eye movements is an important method in the evaluation and topical diagnostic procedure of several vestibular lesions. The aim of the study was to compare the electronystagmographical results of the optokinetic and the smooth pursuit eye-movement, and their sensitivity in several vestibular disorders. The patients were divided into five groups: right...

Vestibular activation is found in diverse cortical areas. To characterize the pathways and types of signals supplied to cortex, we recorded responses to rotational and/or translational stimuli in the macaque thalamus. Few cells responded to rotation alone, with most showing convergence between semicircular canal and otolith signals. During sinusoidal rotation, thalamic responses lead head veloc...

INTRODUCTION Chronic kidney disease is a slowly progressive disease that causes irreversible loss of renal function and is considered a public health problem worldwide. OBJECTIVE To evaluate the vestibular behavior in patients with chronic kidney disease undergoing renal transplantation. METHODS A retrospective cross-sectional study was performed. Thirty patients were evaluated, 33.3% femal...

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...

Sudden, spontaneous, unilateral loss of vestibular function without simultaneous hearing loss or brain stem signs is generally attributed to a viral infection involving the vestibular nerve and is called acute vestibular neuritis. The clinical hallmarks of acute vestibular neuritis are vertigo, spontaneous nystagmus, and unilateral loss of lateral semicircular function as shown by impulsive and...

Heading direction is determined from visual and vestibular cues. Both sensory modalities have been shown to have better direction discrimination for headings near straight ahead. Previous studies of visual heading estimation have not used the full range of stimuli, and vestibular heading estimation has not previously been reported. The current experiments measure human heading estimation in the...

Vestibular inputs are constantly processed and integrated with signals from other sensory modalities, such as vision and touch. The multiply-connected nature of vestibular cortical anatomy led us to investigate whether vestibular signals could participate in a multi-way interaction with visual and somatosensory perception. We used signal detection methods to identify whether vestibular stimulat...

The vestibular system has traditionally been thought of as a balance apparatus; however, accumulating research suggests an association between vestibular function and psychiatric and cognitive symptoms, even when balance is measurably unaffected. There are several brain regions that are implicated in both vestibular pathways and psychiatric disorders. The present review examines the anatomical ...

OBJECTIVE This study presents the role of vestibular evoked myogenic potentials (VEMPs) in the vestibular system investigation focused on the function of the saccule and inferior portion of the vestibular nerve. The main goal of the study is to report VEMP findings in different groups of patients with inner ear disorders symptoms and to identify some clinical application of this test in our pat...
