Coordinated landing requires anticipating the timing and magnitude of impact, which in turn requires sensory input. To better understand how cane toads, well known for coordinated landing, prioritize visual versus vestibular feedback during hopping, we recorded forelimb joint angle patterns and electromyographic data from five animals hopping under two conditions that were designed to force ani...

Background: Vestibular function is essential to pilots. But for now there are little method to evaluate otolith function in pilots.Quite recently vestibular evoked myogenic potential (VEMP) test has been introduced to evaluate the saccule and the inferior vestibular nerve function. The purpose of the present study is to investigate the parameters of VEMP in Chinese Air Force fighter pilots so a...

OBJECTIVES/HYPOTHESIS To identify the predictive ability of vestibular function test results on motor performance among hearing-impaired children. STUDY DESIGN Cross-sectional study. METHODS Fifty-one typically developing children and 48 children with a unilateral (n = 9) or bilateral hearing impairment (n = 39) of more than 40 dB HL between 3 and 12 years were tested by the Movement Assess...

CHARGE syndrome is a rare human disorder caused by mutations in the gene encoding chromodomain helicase DNA binding protein 7 (CHD7). Characteristics of CHARGE are varied and include developmental ear and hearing anomalies. Here we report a novel mouse model of CHD7 dysfunction, termed Looper. The Looper strain harbours a nonsense mutation (c.5690C>A, p.S1897X) within the Chd7 gene. Looper mice...

24 After vestibular labyrinth injury, behavioral measures of vestibular function partially 25 recover through the process of vestibular compensation. The current study was 26 performed to improve our understanding of the physiology of macaque vestibular 27 nucleus neurons in the compensated state (>6 weeks) after unilateral labyrinthectomy 28 (UL). The responses of neurons to sinusoidal yaw rot...

The cervico-ocular (COR) and active and passive vestibulo-ocular reflexes (VOR) were measured in seven patients with spasmodic torticollis (ST) and six normal controls. The COR was found to be weak or absent in both groups. The VOR gain was similar in the two groups but five patients had a significant asymmetry of the response. There was no evidence of abnormal cervico-vestibular interaction du...

INTRODUCTION Cochlear implants are undeniably an effective method for the recovery of hearing function in patients with hearing loss. OBJECTIVE To describe the preoperative vestibular assessment protocol in subjects who will be submitted to cochlear implants. METHODS Our institutional protocol provides the vestibular diagnosis through six simple tests: Romberg and Fukuda tests, assessment f...

The vestibular system of the mammalian inner ear senses angular and linear velocity head enables animals to maintain their balance. Vestibular anatomy has been studied extensively in order link its structure particular kinds locomotion. Available evidence indicates that, primates, slow-moving species show higher levels variation than fast-moving taxa. We analysed intraspecific morphological flu...

Removal of a vestibular organ (unilateral labyrinthectomy, UL) in the lamprey results in a loss of equilibrium, so that the animal rolls (rotates around its longitudinal axis) when swimming. Owing to vestibular compensation, UL animals gradually restore postural equilibrium and, in a few weeks, swim without rolling. Important elements of the postural network in the lamprey are the reticulospina...
