Outline of Final Research Achievements

Attention has been drawn to using near-infrared spectroscopy to measure prefrontal activity. However, the measurement system in an outdoor high-illumination environment has not yet been established. The purposes of this study were to establish a prefrontal activity measurement method using near-infrared spectroscopy in an outdoor high-illumination environment and perform measurement experiments in such an environment. In a period of good weather from July to September, experiments were performed on 81 subjects in urban and forest areas.
We found that prefrontal activity could be measured in an urban area in a high-illumination environment by shading the forehead and improving devices and tools and that prefrontal activity differed between urban and forest areas.
