The change in brain blood volume during a stressful task was measured by using Near Infra-Red Spectroscopy(NIRS)which monitors concentration changes in oxygenated hemoglobin(HbO_2)and deoxygenated hemoglobin(Hb)levels in the brain. To operate a flight simulator is a complex task and well-reflected real world, which is different from the task in a laboratory. Nine pilots landed a flight simulator in a crosswind of which the velocity was varied as four conditions from the light to strong. HbO_2 obtained from left forehead was increased as a function of wind velocity. Few or no changes were seen in HbO_2 from right forehead of Hb from both the left and right forehead. The results of this study showed that the brain blood volume was affected by mental stress which depended on the difficulty of the task. An assessment of mental stress may be able to monitor an increase in HbO_2 in the left forehead by NIRS in the field.
