Well said. What freaks me out about electrical brain stimulation is the brain's well-known capacity for adaptation in response to repeated stimuli. What happens when the brain gets used to the stimulation, or even comes to depend on it? It happens with caffeine, after all. Who's to say it can't happen with an exogenously generated electrical current? I'm excited for the possibilities here, but I'm in no hurry to be a guinea pig.
