A recent article posted on IEEE Spectrum addresses the controversy surrounding tDCS on whether it is in fact doing what we think it’s doing—stimulating an intended area of the brain via weak currents that traverse through the many layers between the electrodes on the scalp and the cortical surface.
Dr. Myles Mc Laughlin of the Belgian University KU Leuven, proposes a new and controversial way of approaching tDCS treatment’s effects on users; stating that he believes the effects of tDCS are definitely real, however the mechanism by which neuromodulation occurs, is actually through stimulating peripherals nerves right underneath the skin, and that signal is then relayed to the brain.
