Abstract
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.The comparative study of the different terms obtained shows changes on the cortical electrical activity under different stimulations.
There is an occipito-parietal cerebral area related with spatial orientation of the individual which establishes an interrelation among sensorial kinaesthetic, vestibular and visual afferentias.
The Virtual Reality Stimulation in Motion Sickness Patients implies the beginning of a new way for the study of the modulation of vestibular cortical activity under visual 3D stimulations.
