Four types of moving patterns of a circle, started from the center of a CRT, were presented at random order to the subjects. The movement patterns of a circle were downward, upward, rightward and leftward. Electroencephalograms (EEG) were recorded in the meantime. The equivalent current dipole localization (ECDL) was done on each EEG to estimate the source. ECDs were localized to the MT, to the intraparietal sulcus (IPS), to the precentral gyrus (PrCG). Further more, ECDs were localized to the frontal eye field (FEF) and superior colliculus (SC). This tendency is observed for all the subjects and at each directional movement. And the localized ECDs that were localized to the same areas and almost the same latencies after PrCG had the opposite directions between upward and downward movements, and between rightward and leftward movements.
