Individualized EEG-based tACS frequency matching may improve stimulation effectiveness

Evidence

Future studies may identify which tACS parameters (e.g., single or dual channel tACS, 4 or 10 Hz frequency) are most effective and systematically optimize them on an individual basis in order to maximize possible perceptual benefits. For example, the tACS frequency could be chosen to match the individual’s dominant ongoing cortical frequency as identified beforehand with EEG (Zaehle et al. 2010 ; Ali et al. 2013 ). Similarly, tACS electrode positions could be chosen based on more realistic current flow simulations using as head model the individual’s anatomy obtained beforehand with MRI (e.g., (Wagner et al. 2014 )). — Dijk, Pim van, Physiology, Psychoacoustics and…, 4807
