Relationship between the colors of the light and the brain actiity measured by NIRS

Abstract

This study aims to confirm the relevance between the colors of the light (red, blue, green, white) and the brain activity of the person who watches the light. To investigate the effect of light colors, this study conducted the examinations including subjective evaluation and brain activity measurement using the NIRS (near-infrared spectroscopy). Our finding suggests that the subjects’ preference and arousal degree of the light environment can be objectively evaluated via frontal lobe brain activity measurement.
