Bullies bruise brains, not just egos

Bullying and other types of chronic social stress affect gene activity in the brain, suggests a new study in mice. The changes may lead to persistent social anxiety.
'Just as alcohol affects your liver, stress affects your brain,' said lead researcher Yoav Litvin of Rockefeller University in New York. The anxiety that can result from being teased and otherwise treated poorly is organically based, Litvin said, meaning it arises from physical changes in the brain. - msnbc.com
