Recently, transcranial direct current stimulation (tDCS) or the non-invasive targeting of weak direct current (DC) to specific brain regions has received media attention. Among the scientific research community, tDCS has been a subject of great interest owing to its usage ease, relative inexpensiveness, and encouraging research results on a range of functions. Studies have seen tDCS accelerate learning, reduce symptoms of dementia, and improve attention in those with Attention Deficit Disorder (ADD). Understandably, a coinciding rise in the DIY community has also prompted an increase in consumer devices available for home use in hopes of mimicking tDCS's potential neuroenhancement ...
