A Discussion of tACS Literature
State-dependent effects of transcranial oscillatory currents on the motor system: What you think matters.
Fuerra, Matteo, Patrizio Pasqualetti, Giovanni Bianco, Emiliano Santarnecchi, Alessandro Rossi, & Simone Rossi. 2013. State-dependent effects of transcranial oscillatory currents on the motor system: What you think matters. J Neurosci. 33(44): 17483-9.
Summary: Tested MEPs under conditions of rest and motor imagery. The researchers applied tACS at 5, 10, 20, & 40 Hz to the left motor cortex, and to the parietal cortex as an active control. TACS delivered at 5 and 20 Hz demonstrated a double dissociation in effect based on motor imagery. 20 Hz tACS increased MEP amplitudes greater at rest, whereas 5 Hz tACS increased MEP amplitudes most during motor imagery.

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.
