Assessment of the Effect of Transcranial Direct Current Stimulations (tDCS) in Focused Attention Enhancement Using Event-Related Potentials

Abstract

frequency domains feature in every s timulation type were extracted from ERP components. Correlation between percentage changes and the subject’s IVA tes t results were calculated before and after applying tDCS. Results: The result showed that Beta energy significantly increased after applying tDCS. Furthermore, a significant correlation was observed between beta energy and auditory omission error in FP1 channel. Conclusion: tDCS decreases omission error and increases beta energy in auditory s timulation, which then leads to the improvement of focus attention. Further s tudies are needed to assess the effect of tDCS on the improvement of attention in auditory attention deficit.
