摘要

从ERP分量中提取每5种刺激类型的频域特征。计算应用tDCS前后百分比变化与受试者IVA测试结果的相关性。结果:经tDCS处理后β能明显升高。此外,FP1通道的β能量与听觉遗漏误差存在显著相关。结论:tDCS减少了听觉刺激的遗漏错误,增加了β能量,从而导致注意力集中的改善。tDCS对听觉注意缺陷的改善效果有待进一步研究。

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