经颅直流电刺激 (tDCS) 对改善注意力和工作记忆的影响通常是混合的且很小，这可能是由于蒙太奇、刺激参数和结果测量的研究之间存在差异。tDCS 蒙太奇是决定目标大脑区域刺激程度和强度的重要参数。本研究旨在检验使用三种不同的蒙太奇来调节注意力和工作记忆表现的效果：双额叶、宽额叶和宽顶叶。93 名健康成年人参加了平衡交叉研究。在执行 1- 和 2-back 任务期间，参与者接受了主动和假 tDCS，以及双额叶、宽额叶或宽顶叶蒙太奇。2  = 0.06）。TDCS 蒙太奇并未显着降低 1-back 任务的性能。tDCS 的认知效果因蒙太奇、任务和结果测量而异。在 Broad-frontal 蒙太奇中将阴极放置在头外的 TDCS 可能有益于改善工作记忆。

The effects of transcranial direct current stimulation (tDCS) for improving attention and working memory have been generally mixed and small, potentially due to variability between studies with montages, stimulus parameters and outcome measures. The tDCS montage is an important parameter which determines the degree and intensity of stimulation in targeted brain regions. This study aimed to examine the effects of using three different montages for modulating attention and working memory performance: Bi-frontal, Broad-frontal and Broad-parietal. Ninety-three healthy adults participated in a counterbalanced cross-over study. Participants received both active and sham tDCS with either the Bi-frontal, Broad-frontal or Broad-parietal montage during performance of both a 1- and 2-back task. TDCS montage moderated 2-back working memory reaction time performance, though not accuracy, with faster reaction times observed for active compared to sham tDCS with the Broad-frontal montage only (F (1,90) = 5.26, p = .024, η2 = 0.06). TDCS montage did not significantly moderate performance on the 1-back task. The cognitive effects of tDCS varied according to montage, task, and outcome measure. TDCS administered with the cathode placed extracephalically in a Broad-frontal montage may be beneficial for improving working memory.
