Recently in Japan, the occurrence of traffic accidents by elderly drivers has become a social problem. It has been reported that traffic accidents caused by elderly drivers are caused by decline of cognitive impairment and physical function due to ag

Recently in Japan, traffic accidents caused by elderly drivers have attracted public attention. Elderly drivers are judged whether they can continue driving based on the cognitive test results at the renewal of their driver's license. However, it has

In this study, we measured brain activity using near-infrared spectroscopy (NIRS) when a person was feeling discomfort caused by vibrations. We used the variance in oxygenated hemoglobin (oxy-Hb) levels as an evaluation index. Correlation coefficient
