Executive function is the ability to change one’s behavior in order to achieve a goal, which is supported by the prefrontal cortex (for review, Abdullah et al., 2021). Transcranial Direct Current Stimulation (tDCS) is a noninvasive brain stimulation technique that changes the likelihood of neuronal firing by sending current through at least two electrodes on the scalp. Prior work in our lab found no enhancement of executive function on healthy participants when at- tempting to stimulate the dorsolateral prefrontal cortex using anodal tDCS with the F3-RSO montage (Darling et al., 2020). However, current modeling suggests that the C3-RSO montage may be more likely to stimulate dorsolateral prefrontal cortex (Datta et al., 2012). Therefore we examine whether using the C3-RSO montage to target the prefrontal cortex could enhance executive function in healthy participants.
