Abstract Objectıve The objective of this study is to obtain normative data the masseter vestibular-evoked myogenic potential (mVEMP) test in healthy individuals without hearing loss and dizziness compare responses with cVEMP test. Methods Twenty (10 males 10 females) aged 20–30 years auditory vestibular disorders participated study. First, mVEMP then tests were applied who voluntarily Results L...

INTRODUCTION There is described a transient nystagmus provoked by shaking the head in the horizontal plane for a few seconds in both normal subjects and patients that is called Head Shaking Test (HSN) as a diagnostic tool for vestibular dysfunction. HSN is generally accepted that is generated by an asymmetrical peripheral vestibular input and a central velocity storage mechanism, which integrat...

OBJECTIVES To investigate whether vibrational impulse stimuli applied to the skull can be used to evoke the vestibulo-ocular reflex (VOR) and detect vestibular lesions. METHODS Twenty four patients with unilateral vestibular loss (UVD), five with bilateral vestibular loss, two with ocular palsies, and 10 healthy subjects participated. Vibrations of the skull were induced with head taps and wi...

Acute unilateral vestibulopathy, or vestibular neuritis, is the second most common cause of vertigo. To quantify the involvement of the different semicircular canal (SCC) afferents in this disease, we studied the three-dimensional (3D) properties of the vestibuloocular reflex (VOR) in 16 patients 3-10 days after onset of symptoms. Using 3D magnetic search coil eye movement recordings, we measur...

The accuracy with which the vestibular system anticipates and compensates for the visual consequences of translation during forward and backward movements was investigated with transient motion profiles in rhesus monkeys trained to fixate targets on an isovergence screen. Early during motion when visuomotor reflexes remain relatively ineffective and vestibular-driven mechanisms have an importan...

A postural control system in the lamprey is driven by vestibular input and maintains the dorsal-side-up orientation of the animal during swimming. After a unilateral labyrinthectomy (UL), the lamprey continuously rolls toward the damaged side. Normally, a recovery of postural equilibrium ("vestibular compensation") takes about 1 mo. However, illumination of the eye contralateral to UL results i...

background chronic vestibular dysfunction is a frustrating problem in the elderly and can have a tremendous impact on their life, but only a few studies are available. vestibular rehabilitation therapy (vrt) is an important therapeutic option for the neuro-otologist in treating patients with significant balance deficits. objectives the purpose of this study was to assess the effect of vestibula...

Nerve injury induces a reorganization of subcortical and cortical sensory or motor maps in mammals. A similar process, vestibular plasticity 2 mo after unilateral section of the ramus anterior of N. VIII was examined in this study in adult frogs. The brain was isolated with the branches of both N. VIII attached. Monosynaptic afferent responses were recorded in the vestibular nuclei on the opera...

bstract—Depression is characterized by alterations in the ircadian secretion of hormones, sleep and motor activity, all f which are regulated by suprachiasmatic nuclei (SCN). The estibular system in the inner ear registers the amount of otor activity. To test the integrity of this motion sensitive ystem in depression, we studied the vestibulo-ocular reflex VOR) in depressive patients who were n...

INTRODUCTION Despite its high incidence and severe morbidity, the physiopathogenesis of adolescent idiopathic scoliosis (AIS) is still unknown. Here, we looked for early anomalies in AIS which are likely to be the cause of spinal deformity and could also be targeted by early treatments. We focused on the vestibular system, which is suspected of acting in AIS pathogenesis and which exhibits an e...
