Abstract

A 16-channel near-infrared spectroscopy (NIRS) was used to measure concentration changes of oxygenated and deoxygenated hemoglobin (oxy-HB and deoxy-HB) in prefrontal area while the subjects were performing mental works. Thirty healthy college participants were administered two mental arithmetic tasks while the changes of concentration on oxy-HB and deoxy-HB were measured. Oxy-HB increased during the mental works, and the increases of oxy-HB were greater in male subjects than in female subjects during the difficult task. These results suggest that NIRS is sensitive to evaluate the oxy-HB activity of prefrontal cortex during mental works.
