The effects of visual stimulation in the form of vertically or horizontally arranged wooden interior wall images using a large plasma display: Crossover test - Visual stimulation effects of vertically or horizontally arranged wooden interior wall images using a large plasma display

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.
