| الوصف: | Background: quality of record of electronystagmography during the studies of the vestibular system depends on the proper selection and placement of the electrodes, which are usually located at specific points in the eye socket to allow the collection of the variation of electric potential generated between the cornea and the retina caused by the jerking of the induced or natural nystagmus. Objective: to present the experimental results that demonstrate this influence by quantifying the effect on the records. Development: it was used the technique of visual stimulation with moving target at different frequencies of movement, and the records were made under the lighting conditions established in the published standard for electrooculography, using a two-channel amplifier with a sampling frequency of 1 kHz. The results obtained reflect the change in the tensions in the records according to the electrode placement zone, there being an optimal zone for the adequate record of electronystagmography. Conclusions: the affectation by zones in the records in the temporal domain and the frequency was demonstrated, and its influence in the generation of errors in the topographic diagnosis of diseases that affect the Vestibular System.
