Abstract

With the brain electrical activity mapping, we started to create typical patterns of potentials distributions on the scalp during various neurootological experiments. We are applying this technique for spatiotemporal analysis of cerebral evoked potentials due to vestibular stimulation. We obtain the vestibular evoked potentials (VbEP) using for the stimulation, the rotatory chair. We control it, with an external computer, that by means of an interactive program builds different sort of stimuli varying each one of the stimulus components. The electrodes are distributed on the scalp in agreement with the international system 10/20. We recognize with security, 4 positive-negative waves in a period among 70 to 490 ms. We designate the waves N1, N2, P2, N3 and N4. Vestibular evoked potentials is a newly developed tool, which we also can utilize for differentiating central and peripheral vestibular diseases.
