Abstract
In automobiles, Radiation and convection of heat due to disturbance such as sunlight is stronger than indoor environment. The thermal environment in automobiles is non-uniform and locally inhomogeneous thermal environment. Therefore, local thermal environment evaluation is important for evaluating the thermal environment in automobiles. So we aim to evaluate local thermal environment by analysis of brain activity. And the final goal is development of the air conditioning control system using the results. In this paper, we describe analysis of brain activity during local cold stimulus. In our experiments, we measured oxyHb in the prefrontal cortex and the primary somatesthic cortex during subject' finger touch different temperature aluminum plates. The results reveal that oxyHb change in left hemisphere near parietal region of the brain by large temperature difference.
