Examining state-dependent effects of transcranial direct current stimulation on visual search and executive function tasks

Conclusions

This outcome does not provide direct support for state-dependency or activity-selectivity models of tDCS effects on cognitive outcomes. We discuss the possibility that behavioral patterns supporting these mechanistic models may only be found when the priming and outcome tasks share critical neurocognitive features. Overall, we found no evidence that offline (pretask) tDCS targeting the right parietal or left dorsolateral prefrontal induces reliable changes in visual search or inhibitory control behavior, and this pattern is not modulated by state-dependency induced by priming task-related activity.
