Researchers Find Clue to How Alcohol Interacts With Brain
Researchers believe they have identified the area of the brain that determines a preference for alcohol, perhaps the first step in an eventual treatment for alcoholism.In a study published Monday in the Society for Neuroscience journal eNeuro, researchers said they were trying to determine why some people can consume alcohol every day without developing dependence while less frequent drinkers develop a dependence.The researchers, from the University of Massachusetts, offered a test group of rats intermittent access to a 20 percent alcohol solution, then trained them to self-administer both 10 and 20 percent solutions of alcohol, as well as a sugar solution as a reward. They then were able to determine which rats were high or low alcohol consumers and divide them accordingly.The researchers monitored the orbitofrontal cortex (OFC) activity in…
