In this experiment, we measure brain activities by Near-infrared spectroscopy (NIRS) when a person is feeling the discomfort caused by vibration. We use a variation of oxygenated hemoglobin (oxy-Hb) as an evaluation index. As a result, two kinds of trends were seen in the brain activities of test subjects. At the other groups increase of oxy-Hb levels is remarkable in prefrontal cortex outer portion, reduction of oxy-Hb levels is pronounced in the medial prefrontal cortex in the other group. These brain reactions were found to be that there is discomfort and the high correlation that people feel the vibration.
