Abstract :
A moving white circle on a CRT was presented to subjects. Moving patterns were downward, upward, rightward and leftward. A random movement of the circle was presented to subjects in comparison of other movements. These five movements were presented at random to the subjects. Meantime, electroencephalograms were recorded. The data was summed in each movement and the equivalent current dipole localization (ECDL) was done to estimate the source. From the results, the dipoles was estimated on the MT at latency from 80 ms to 120 ms, and after on the intraparietal sulcus, on the precentral gyrus and on the frontal eye field.
