Effects of Individualized Theta-tACS on a Working Memory Training at SCD

Transcrainal alternating current stimulation (tACS) is a non-invasive brain-stimulation where weak sinusoidal electric current with frequencies within the EEG-range is applied over electrodes on the scalp. In the study we use the DC-Stimulator MC, neuroConn, Ilmenau for the stimulation.The device is authorized as medical device for the application on humans in Germany with a CE-Identification. We use two circular (area each = ca. 7.07 cm\^2) and two ring-shaped (area each = 40 cm\^2) rubber electrodes. Impedances are kept \< 15 kOhm.
