| Number of participants that the trial has enrolled | 28 | ||||||
| Results | 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. |
