Researchers from the universities of Bradford and Sheffield in the U.K. and the Institute of Medicine and Neuroscience at Julich, Germany, have been investigating the effects of tranquil, natural environments and stressful artificial ones on brain activity. They showed participants in their study pictures of waves breaking on a beach and traffic rushing down a motorway with the same background noise designed to sound similar to waves and traffic noise. The participants' brains were scanned while they watched the videos and the study found that the natural, tranquil scenes caused different brain areas to become connected with one another - indicating that these brain regions were working 'in sync.' The people who watched the traffic on the motorway, however, showed disrupted connections within their brain.
