Figure 1 (IMAGE) Max Planck Institute for Psycholinguistics Caption Top: Stimulation electrodes were centered over CP6 (right hemisphere) and CP5 (left hemisphere) (41). Middle: The interhemispheric phase synchrony was manipulated using 40Hz TACS with an interhemispheric phase lag of 0° (TACS 0°) or 180° (dotted line, TACS 180°). The colors represent the polarity (positive = red; negative = blue) of the current for the time stamp highlighted by the dotted line. Bottom: Simulation of the electric field strength induced by bi-hemispheric TACS in a template brain. RH: Right hemisphere; LH: Left hemisphere Credit Basil Preisig Usage Restrictions None License Licensed content Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert! by contributing institutions or for the use of any information through the EurekAlert system.
