PROBLEM TO BE SOLVED: To provide a visual evoked potential signal detection system capable of substantially reducing a burden of an observer by suppressing the dazzling and flickering of flashing lights, being extremely suited to a long use and exerting excellent practicality.SOLUTION: This visual evoked potential signal detection system includes an observation object 10 disposed with a plurality of light sources 11, 11, 11, 11, 11and 11, and a signal processing section 20 for processing brain wave signals of the observer OB viewing the light sources 11. As for the observation object 10, the light sources are flashed at such a flashing frequency that, though being flashed, the flashing lights are viewed by the observer OB as if they are continuously lit. |
