They’ve also presented their tDCS results as consistent with a specific proposed mechanism of action: modulating the timing of neurons spiking. Moreover, they measured local field potentials (LFP) and associated changes in power and coherence of some frequency bands with the accelerated learning observed. LFP is similar to the electroencephalograms (EEG) we’re more familiar with here, with the main difference being that they are measured using thin electrodes embedded in brain tissue rather than on the surface of the scalp. It’s by no means a complete and testable model of how tDCS may enhance learning, but it looks a lot like progress.
