The study, published in Nature, was conducted by scientists at the Intramural Research Program of the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health, and the University of California, San Francisco.

NIH study indicates reverse impulses clear useless information, prime brain for learning
When the mind is at rest, the electrical signals by which brain cells communicate appear to travel in reverse, wiping out unimportant information in the process, but sensitizing the cells for future sensory learning, according to a study of rats conducted by researchers at the National Institutes of Health.

Scientists may be better able to study how heavy drinking damages the liver using a new mouse model of alcohol drinking and disease developed by researchers from the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health. The model incorporates chronic and binge drinking patterns to more closely approximate alcoholic liver disease in humans than any existing method. A report of the new model appears in the March issue of the journal Nature Protocols.
