it has been shown recently that loud clicks evoke myogenic potentials in the tonically contracting sternocleidomastoid muscles. studies have suggested that these potentials are of vestibular origin, especially of the saccule and inferior vestibular nerve. a pilot study was undertaken in our hospital to record vestibular evoked myogenic potentials (vemp) for the first time in iran. eighteen heal...

background :preterm birth is a significant global health problem with serious short- and long-term consequences. this study examined the long term effects of preterm birth on vestibular evoked myogenic potentials (vemps) among preschool-aged children.   methods : thirty-one children with preterm and 20 children with term birth histories aged 5.5 to 6.5 years were studied. each child underwent v...

The human vestibular cortex has mostly been approached using functional magnetic resonance imaging and positron emission tomography combined with artificial stimulation of the receptors or nerve. Few studies have used electroencephalography benefited from its high temporal resolution to describe spatiotemporal dynamics information processing first milliseconds following stimulation. Evoked pote...

BACKGROUND Vestibular reflexes, evoked by human electrical (galvanic) vestibular stimulation (EVS), are utilized to assess vestibular function and investigate its pathways. Our study aimed to investigate the electrically-evoked vestibulo-ocular reflex (eVOR) output after bilateral and unilateral vestibular deafferentations to determine the characteristics for interpreting unilateral lesions suc...

OBJECTIVE To investigate saccular function using vestibular evoked myogenic potentials in children with congenital or early acquired sensorineural hearing loss. DESIGN Retrospective cohort study. SETTING Pediatric tertiary referral center. PATIENTS Twenty-three children with bilateral sensorineural hearing loss (severe to profound in 22 cases, moderate in 1 case) underwent evaluation of s...

PURPOSE OF REVIEW This article reviews the literature on vestibular-evoked myogenic potential testing, a short latency electromyogram evoked by high acoustic stimuli and recorded via surface electrodes over the sternocleidomastoid muscle. Applications and refinements of this technique are described for different pathologies and in adults and children. RECENT FINDINGS Various techniques for el...

Acoustic sensitivity of the vestibular apparatus is well-established, but the contribution of vestibular receptors to the late auditory evoked potentials of cortical origin is unknown. Evoked potentials from 500 Hz tone pips were recorded using 70 channel EEG at several intensities below and above the vestibular acoustic threshold, as determined by vestibular evoked myogenic potentials (VEMPs)....
