Abstract In the last decade, an increasing number of studies have suggested that transcranial direct current stimulation (tDCS) may enhance brain function in healthy individuals and ameliorate cognitive other symptoms patients suffering from various medical conditions. This, along with its presumed safety, simplicity affordability, has generated great enthusiasm amongst researchers, clinicians, patient populations public (including a growing “do-it-yourself” community). However, discussion about effectiveness ethics tDCS thus far been confined to small groups researchers bioethicists. We conducted international online survey targeting opinions using who were asked rate technique’s efficacy different contexts. also surveyed ethical concerns, self-enhancement availability. 265 complete responses received analyzed statistically thematically. Our results emphasize potential uses clinical research contexts, but highlight emerging methodological safety challenges need for improved communication between bioethicists regard regulation device. Neither media reputation as “miracle device” nor concerns expressed recent neuroethical publications entirely borne out expert opinion.
