Abstract :
In this study a magnetoencephalograph, which has excellent time resolution, was used to confirm the difference in the responses towards two kinds of visual stimuli which had different recognition levels. The chaos characteristics contained in MEG were then considered. A clear difference was confirmed between the target stimulus and the non-target stimulus in the MEG response wave and the correlation dimension value
