Nicely done (for a media outlet) six week experiment to test efficacy of HaloNeuro‘s Halo Sport tDCS device. Elise’s takeaway is that she wishes the effect was a little more dramatic. But her trainer tells her that extra 1-1/2″ is actually significant. Certainly in pro sports settings I’m sure it would be. Nice overview of hypothetical understanding of how tDCS works. She also interviews HaloNeuro co-founder Daniel Chao and Olympic volleyball athlete Kim Glass. Elise on Twitter
