Stimulation of the sense of sight with a steady light signal evokes in the nervous system, and particularly in the primary visual cortex, the phenomenon called Steady State Visualy Evoked Potentials (SSVEP). Presented method and equipment allow synchronous recording of stimulatory and evoked (SSVEP) signals. As the realtime controller a DSM-51 unit was used. This controller serves two functions: (1) generates a sinusoidal signal influencing the brightness of the two three-color LED sets, (2) decides on one of the 37 light colors of the LED sets. A special adapter has been developed to convert signals coming from the DSM-51 into signals suitable to control the LED sets. The adapter generates an additional signal fed directly to an EEG amplifier. This signal is recorded synchronously with the EEG signal coming from the electrocap. As the EEG amplifier a 16-channel Mindset 1000, produced by Nolan Computer Systems, was used. The proposed registration method allows precise identification and mutual matching of the stimulus and evoked signals, and thus their effective analysis.
