ABSTRACT |
Loud click or tone burst sound can activate vestibular receptor and evoke reflex changes in tonic electromyographicactivity within the stenocleidomastoid muscles. This reflex is assumed to originate in the saccule, the afferent pathwaysbeing the inferior vestibular nerve, and the efferent pathways the vestibulospinal tract. Averaging these muscularresponses allows vestibular evoked myogenic potentials (VEMP) to be obtained. The earliest response ipsilateral to aloud click, p13n23, is dependent upon vestibular activation, specifically saccular afferents. These new techniques arebeginning to be applied clinically in the patient of vestibular neuritis, Meniere |
