[Vestibular evoked potentials in people].
In the article had been presented the structure and functioning of a prototype system for stimulation and registration vestibular evoked potentials, and the first recording of evoked vestibular potentials (VsEPs) in human beings. This system consist of a original stimulator accelerated for the stimulation of vestibular organ, modul registratory VsEPs as well as string elements and synchronizing stimulation with recording. IMB PC 486 is quickly process of investigation with help of standard interface and a original computer programme. Vestibular organ had been evoked by 200 to 500 cyclicly repealed angular decelerations of 4000 degrees/s2. During investigation white noise was used for masking to avoid the evoking of auditory potentials. Seven of the examined healthy persons (including one deaf person whose vestibular organ was not damaged) had registered a response consisting of several waves with vertex positive peaks. The first two waves P1 and P2 with the mean value 2.02 ms and 5.6 ms are most often during in the 10 ms. The registered deaf persons response does not differ from the record of healthy persons.
