Not Applicable

• Conditions: Healthy person

• Registration Number: JPRN-UMIN000034011
• Lead Sponsor: Center for Environment, Health and Field Sciences, Chiba University

Brief Summary

It was found that visual stimulation with either of the wooden interior wall images induced a significant decrease in oxy-Hb concentration in the left and right prefrontal cortex compared with the gray image. Furthermore, the subjective evaluation showed that the wooden-wall images provided a significantly more "comfortable," "relaxed," and "natural" impression than the gray image and decreased the negative mood states.
