Results
Seascape viewing significantly increased the left right difference (LRD) in oxy-Hb concentrations, indicating left-dominant prefrontal activation relative to the control. It also increased comfort and relaxation and improved mood states. Correlation analyses showed that LRD was positively correlated with comfort and relaxation.
