Can Alcohol Help the Brain Remember? Science Says Yes!
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.
