Alcohol Helps the Brain Remember, Says New Study

AUSTIN, Texas — Drinking alcohol primes certain areas of our brain to learn and remember better, says a new study from the Waggoner Center for Alcohol and Addiction Research at The University of Texas at Austin. The common view that drinking is bad for learning and memory isn't wrong, says neurobiologist Hitoshi Morikawa , but it highlights only one side of what ethanol consumption does to the brain. "Usually, when we talk about learning and memory, we're talking about conscious memory," says Morikawa, whose results were published last month in The Journal of Neuroscience . "Alcohol diminishes our ability to hold on to pieces of information like your colleague's name, or the definition of a word, or where you parked your car this morning. But our subconscious is learning and remembering too, and alcohol may actually increase our capacity to learn, or 'conditionability,' at that level." Morikawa's study, which found that repeated ethanol exposure enhances synaptic plasticity in a key area in the brain, is further evidence toward an emerging consensus in the neuroscience community that drug and alcohol addiction is fundamentally a learning and memory disorder. When we drink alcohol (or shoot up heroin, or snort cocaine, or take methamphetamines), our subconscious is learning to consume more. But it doesn't stop there.
