Vestibular evoked potentials

ABSTRACT Objective. Vestibular evoked myogenic potentials (VEMPs) are now being used worldwide as a reproducible screening test of the otholitic function, particularly to assess the saccular function. They have been employed in patients affected by Paroxysmal Positional Vertigo (PPV), especially in the relapsing form (RPV). Recently, a new test to study otolithic evoked potentials – […]

Die menschliche Gleichgewichtsfunktion wird durch ein sogenanntes Raumkonzept mit Einspeisung von Informationen aus der Gleichgewichtstetrade, nämlich Auge, Vestibularis, Cochlea und Propriozept im menschlichen Hirnstamm gebildet. Ergänzt wird die Gleichgewichtsregulation durch cerebelläre und kortikale Musterverarbeitungsprozesse und Speicherinhalte. Gleichgewichtsfunktionsstörungen können an den verschiedensten Orten der genannten Rezeptoren, wie auch innerhalb des Zentralnervensystemes entstehen. Für die diagnostische Suche […]

Cortical activity has been analyzed on 238 patients consulting on vertigo and motion sickness, who were studied through Vestibular Cortical Evoked Potentials Mapping, Brain Mapping in rest state and Brain Mapping under 3D Virtual Reality Stimulation.

This study was conducted in an attempt to determine the efficacy of neurofeedback (NFB) in the treatment of patients suffering from vertigo or tinnitus. Results indicated that after NFB, power for delta and theta bands was reduced; however, an increase of power was noted for the alpha bands.

It is known that equilibrium disorders caused by involvement of brainstem-cerebellar structures are common in patients with Multiple Sclerosis (MS), but peripheral conditions such as Benign Paroxysmal Positional Vertigo (BPPV), can be sometimes confused with those of central origin. Therefore, an accurate otoneurologic investigation paying attention to differential diagnosis aspects should be performed in these […]

The vestibular pathway, like other sensorial systems, has a cortical representation. In 1985 we have published our first investigation on «Variations of the cortical electrical activity during supramaximal vestibular stimulations».

Last year, we have introduced in our laboratory the vestibular evoked potentials (VbEP) as a new test, in order to facilitate the neurootological diagnosis.
