Modulation of Conflict Processing by Theta-Range tACS over the Dorsolateral Prefrontal Cortex

Figure 1

The color-word Stroop task. After practice trials, the participants performed 600 trials within one session while being stimulated by tACS. They responded as quickly and accurately as possible during the 1.5 s of a single trial. Congruent and incongruent trials appeared equally often and were subcategorized depending on the preceding trial.
