It is very important for development of a brain machine interface to analysis brain activity. In this paper, we present measurement of brain activation responses during weight shifting by near-infrared spectroscopy (NIRS). The subjects shift their weight from side by side, and we measure their brain activation by near-infrared spectroscopy. To evaluate effects of skin blood flow, we used probes with two distinct distances (15mm and 30mm) for NIRS and simultaneously measured skin blood flow. We also measured the position of the center of gravity by the ground reaction force meter. The results showed that oxy-Hb changes were influenced by direction of movement, we also found that NIRS signals generally reflected skin blood flow.
