Humans may be hard-wired to feel at peace in the countryside and confused in cities – even if they were born and raised in an urban area.

According to preliminary results of a study by scientists at Exeter University, an area of the brain associated with being in a calm, meditative state lit up when people were shown pictures of rural settings. But images of urban environments resulted in a significant delay in reaction, before a part of the brain involved in processing visual complexity swung into action as the viewer tried to work out what they were seeing.

The study, which used an MRI scanner to monitor brain activity, adds to a growing body of evidence that natural environments are good for humans, affecting mental and physical health and even levels of aggression.

Dr Ian Frampton, an Exeter University psychologist, stressed the researchers still had more work to do, but said they may have hit upon something significant.
