Scientists: Exhaust fumes disrupt neural connections in the brain Exhaust fumes are harmful to human health. Now it's been proven in terms of the effect these exhausts have on the brain..

Neuropsychologists from the University of British Columbia and the University of Victoria have found that breathing in car exhaust for two hours can disrupt brain connections..

These findings are based on a study of 25 healthy adults who were exposed to vehicle pollution in a laboratory setting.. In another step, participants were also exposed to clean, filtered air..

Computer scans showed that after inhaling the exhaust, connections between areas of the brain that are responsible for functions such as introspection and memory decreased..

“More research is needed to fully understand the functional implications. It is possible that these changes may impair thinking or people's ability to work,” said neuropsychologist Jody Gavrilyuk..

Scientists warn that chronic exposure to polluted air can be detrimental to the brain. This is especially dangerous since up to 99 percent of the world's people live in unclean environments..
