At-home electric headband for depression could go mainstream [News]

A doctor's prescription for clinical depression could one day sound like this: In the comfort of your own home, slip on a brain-zapping headband a few times per week. For 20 minutes, it will send a tiny stream of electricity through your brain. The treatment would be delivered by a userfriendly type of brain stimulation called tDCS (transcranial direct-current stimulation). This mindaltering technique has become a hot topic in neuroscience research over the last decade, and it's now beginning the transition from lab to doctor's office.
