Researchers shed light on anxiety and alcohol intake
...t spends in the closed versus the open arms of the maze
during a 5-minute testing period the greater an animal's level of anxiety, the less open-arm activity it displays. Dr. Pandey and his colleagues also found that levels of CREB, a protein involved in a variety of brain functions, were lower in certai...
