Air pollution can change our brain. It changes how parts of our brain connect with other parts. Research shows this can happen in two hours. A researcher was surprised by his research. Scientists always thought the brain was safe from the harmful effects of air pollution. Now he says air pollution affects the brain.

The study was on 25 adults. They breathed car fumes in a laboratory. Scientists took brain scans of them for two hours. The scans showed that there were fewer connections between the networks we use to think. Another professor worried about how traffic pollution can change the networks in our brain.
