We would surely all love a way to boost our brain power. But new research suggests that one promising experimental method could come with a cost. Using a noninvasive technique to stimulate the brain, researchers found they could enhance learning when they targeted a certain spot. But that also made people worse at automaticity, or the ability to perform a task without really thinking about it. Stimulating another part of the brain had the reverse effect, on both learning and automaticity.
“This tells us something about the human brain,” says lead researcher Roi Cohen Kadosh, a neuroscientist at the University of Oxford, in England. “We can’t ask for everything without paying a price.” The findings were published Tuesday in the Journal of Neuroscience.
