Breathing in air pollution could change our brain. A new study shows that car
fumes(尾气) can change how parts of our brain connect with other parts.
The research is from the University of British Columbia in Canada. Researchers
found that our brain's connectivity(连接性能) can be changed by car fumes in just two
hours. A researcher, Professor Chris Carlsten, was surprised at what he found. He
said. “For many years,scientists thought the brain may be protected from the effect(影
响) of air pollution. This study is the first of its kind in the world. It provides fresh
evidence(证据）showing a connection between air pollution and ‘thinking’.”
The traffic pollution study was on 25 adults. The researchers asked the adults to
breathe in car fumes in a laboratory. The research team took brain scans(扫描) of the
adults for two hours. The scans showed that the networks(网络) in the brain that we use
for thinking and remembering changed.There were fewer connections between the
networks.
Another professor was worried about the result of the research. She
said,"It's concerning to see traffic pollution having an effect on or even breaking these
networks."The researchers said they needed to do more research to see how car fumes
change our brain. They also advised people to close car windows when in traffic.The
brains of the 25 people returned to normal after they breathed clean air.
( )26.What did the researchers find in their study?A. Car fumes stay in our body for a long time.
B. Air pollution has nothing to do with our brain.
