Reduction in Dorsolateral Prefrontal Cortex (DLPFC) blood flow is reported to be seen during the wakefulness to the early stage of sleep, and is often the cause of car accidents. Near-infrared spectroscopy is necessary for measuring DLPFC blood flow, but is not suitable for the daily use due to cost and complexity. To prevent traffic accidents, we proposed a non-restricting and low-cost method for estimating DLPFC blood flow. We made up a formula by applying a multivariate analysis for heart rate and heart rate variability measured by Doppler radars. The correlation between DLPFC blood flow and the estimated value was high in the cases of subjects with decreased DLPFC blood flow.
