[Evaluation of the visual evoked potentials in relation to the type of visual stimulation]

A classification of visual evoked potentials (VEP) in children and adults in response to various types of vision stimulation has been developed. Four major signs underlie this classification: (1) stimulation time frequency; (2) stimulation type; (3) mode of producing the visuals stimulus; (4) mono- or binocular presentation of the stimulus. One more sign can be added to classification: significant parameters of stimulation. Basing on this classification, the author describes the major VEP modalities and gives recommendations on the practical employment of these modalities.
