Research on brain-machine-interfaces (BMIs) is widespread and rapidly growing in concert with the rapid advances of recent years in brain science and engineering, and systems technologies for interactions between human and machine are of major interest. It is very important for development of BMIs to analysis brain activities. In this paper, we present measurement of brain activation response for weight shifting and center of gravity movement trials using near-infrared spectroscopy (NIRS). We measured their brain activations by NIRS. 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 using the ground reaction 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.
