June 11, 2017
(THE CONVERSATION) The first time I heard that shooting electrical currents across your brain can boost learning, I thought it was a joke.
But evidence is mounting. According to a handful of studies, transcranial direct current stimulation (tDCS), the poster child of brain stimulation, is a bona fide cognitive booster: By directly tinkering with the brain’s electrical field, some research has found that tDCS enhances creativity, bolsters spatial and math learning and even language aquisition – sometimes weeks after the initial zap.
For those eager to give their own brains a boost, this...
