"Unfocus" on foc.us: commercial tDCS headset impairs working memory.In this study, we tested whether the commercial transcranial direct current stimulation (tDCS) headset foc.us improves cognitive performance, as advertised in the media.  A single-blind, sham-controlled, within-subject design was used to assess the effect of online and off-line foc.us tDCS-applied over the prefrontal cortex in healthy young volunteers (n = 24) on working memory (WM) updating and monitoring.  For both online and off-line stimulation protocols, results showed that active stimulation with foc.us, compared to sham stimulation, significantly decreased accuracy performance in a well-established task tapping WM updating and monitoring.
