WASHINGTON (AP) � More evidence that bullies aren't good for you.
Scientists watching big [homosexual] mice intimidate small [homosexual mice] have discovered the stress spurs genetic changes in the brain. They say the finding may help research into depression and other mental illnesses.
The experiment suggests a part of the brain linked to addiction also plays a previously unsuspected role in illnesses characterized by chronic anxiety and social withdrawal. Texas researchers report their findings in the journal Science.
In fact, a substance produced in the brain, called BDNF, seems to be the culprit, controlling whether the bullied [homosexual mice] turned into fearful [homosexual] hermits or not.
Neuroscientists at the University of Texas Southwestern Medical Center subjected [homosexual] mice to intimidation. When they shut off BDNF to the [homosexual] mouse brains, the small mice no longer developed the proper fear of the bullies.
