Freeway air causes brain damage

April 8, 2011

Neurobiologists at the University of Southern California have demonstrated that mice show significant brain damage after short-term exposure to vehicle pollution, including signs associated with memory loss and Alzheimer’s disease.

The researchers recreated air with freeway particulate matter under controlled laboratory conditions. They used brain cells in vitro as well as live mice. The particulate matter measured up to 200 nanometers in width.

They found that neurons involved in learning and memory showed significant damage; the mouse brains showed signs of inflammation associated with premature aging and Alzheimer’s disease; and neurons from developing mice did not grow as well.
