Abstract
Objectives The effect of acute transcranial direct current stimulation (tDCS) on cortical attention networks remains unclear. We examined the effect of 20 min of 2 mA dorsolateral prefrontal cortex tDCS (bipolar balanced montage) on the efficiency of alerting, orienting and executive attention networks measured by the attention network test. Materials and Methods A between‐subjects stratified randomized design compared active tDCS vs. sham tDCS on attention network function in healthy young adults. Results Executive attention was greater following active vs. sham stimulation (d = 0.76) in the absence of effects on alerting, orienting, or global RT or error rates. Group differences were not moderated by state‐mood. Conclusion(s) Twenty minutes of active 2 mA tDCS over left DLPFC is associated with greater executive attention in healthy humans.
