Sažetak
In the paper one method of human visual evoked potentials VEP analysis using ‘ chess pattern’ stimulation is described. It is shown that it is possible from recorded surface potentials, by use of an inverse solution, to represent and localize the electric activity of VEP by mathematical model of two separate and independent dipoles. This method of VEP sources localization permits dynamic follow-up of the evoked electrical activity propagation through the brain structures. Also, an excellent correlation of results with expected electrophysiological data indicate the possible applications of this method in the visual system impairment diagnosis.
