The eye movements of those living in Britain are different to those of people living in China, a study has shown.
Scientists at the University of Liverpool, England, and Sichuan University in Chengdu, China, studied the eye movements of Chinese and British people.
They found that a type of eye movement that is rare in British people is much more common in Chinese people.
This suggests there could be slight differences in the brain function of different populations.
Dr Paul Knox, from the Institute of Ageing and Chronic Disease at the University of Liverpool, said 97 per cent of British people, as expected, had a common fifth of a second delay in their eye movements, but only three per cent had a much faster response.
"In our Chinese group, however, 30 per cent had the faster, less common response," he added.
