Researchers Shed Light on Anxiety and Alcohol Intake
Scientists have identified a brain mechanism in rats that may play a
central role in regulating anxiety and alcohol-drinking. The finding,
by researchers supported by the National Institute on Alcohol Abuse
and Alcoholism (NIAAA), part of the National Institutes of Health
(NIH), could provide important clues about the neurobiology of
alcohol-drinking behaviors in humans. A report of the study appears in
the October 3, 2005 issue of the Journal of Clinical Investigation.

"This is an intriguing finding," notes NIAAA Director Ting-Kai Li,
M.D. "These experiments, conducted in rats selectively bred to have a
high affinity for alcohol, help us address questions about the
potential role that anxiety might play in human alcoholism. These
molecular studies also may reveal potential targets for therapy of
anxiety and alcoholism."
