| Outline of Final Research Achievements |
Spatially resolved near-infrared spectroscopy (NIRS) is used widely to measurement of regional cerebral oxygenation, but the NIRS signal is influenced by changes in extra cranial blood flow. We estimated an accurate cerebral oxygenation during exercise and cognitive task using new algorithm which eliminates the influence of the extra cranial blood flow on the NIRS signals. Our findings suggest the possibility that the new algorithm excludes the influence of skin blood flow on the NIRS-determined O2Hb even during condition with increased cerebral oxygenation.
