Changes in the oxyhemoglobin (oxy-Hb) concentrations in the right prefrontal cortex. The oxy-HB concentrations of participants during visual stimulation with vertical and horizontal wooden-wall images and a gray image (control) were measured every second over a 90-s period. The difference in each data point from the mean value during the last 30 s of the rest period (gray area) is presented in this chart. Data are expressed as means ± standard errors (N = 28)
