A Discussion of tACS Literature
The importance of timing in segregated theta phase-coupling for cognitive performance
Polanía, Rafael, Michael A Nitsche, Carolin Korman, Giorgi Batsikadze, and Walter Paulus. 2012. 'The importance of timing in segregated theta phase-coupling for cognitive performance', Current Biology, 22: 1314-18.
Summary: Neural oscillations are theorized to be necessary for interregional communication. Synchrony between the frontal and parietal cortex increases during cognitive control. Polanía et al. used a novel three electrode montage to synchronize the frontal and parietal cortex in-phase or anti-phase. Participants receive the stimulation during performance of a working memory task. In-phase stimulation increased behavioral performance and anti-phase stimulation decreased performance.

Every week, there are new and exciting scientific papers published on studies that investigated tACS. Reading and understanding these papers unfortunately requires both access to (sometimes quite expensive) scientific journals and in-depth "insider knowledge." Our goal is to share with you brief summaries of tACS studies that give you a big-picture idea of what the publications are about. There are too many studies to feature all of them but we will continuously update this page. If you have a specific study you would like to get featured, please contact us. The contributors are personnel from the Frohlich Lab and the Carolina Center for Neurostimulation.
