In Time's "Healthland" blog, reporter John Cloud described his experience with transcranial direct current stimulation (tDCS). "The scientists who demonstrated tDCS for me — Ingrid Olson and David McCoy of Temple's psychology department and David Wolk, a neurologist at the University of Pennsylvania — recently co-authored an article for the November issue of Neuropsychologia about the use of tDCS to improve memory. The paper shows that just 15 minutes of tDCS can help with a common problem: [...] remembering people's names," wrote Cloud.
