UNLABELLED
Non-invasive brain stimulation (NIBS) techniques such as transcranial direct current stimulation (tDCS) allow for investigating the functional involvement of specific brain areas in mental arithmetic. In this study, we employed for the first time high-definition (HD)-tDCS, which offers enhanced spatial precision, to explore the functional roles of the left and right intraparietal sulcus (IPS) in mental arithmetic. A total of 25 participants underwent anodal left IPS, anodal right IPS, and sham stimulation in separate sessions in counterbalanced order while solving single- and multi-step addition and subtraction problems. We found that stimulation of the left IPS, but not the right IPS or sham stimulation, improved arithmetic performance speed. These results provide further evidence for the functional involvement of the left IPS in a broad range of arithmetic tasks and highlight the potential of NIBS for cognitive enhancement.

经颅直流电刺激（tDCS）等非侵入性脑刺激（NIBS）技术能够用于研究特定脑区在心算中的功能作用。在本研究中，我们首次采用了具有更高空间精度的高清（HD）-tDCS，以探究左右顶内沟（IPS）在心算中的功能作用。共有25名参与者在解决单步和多步加减法问题时，以平衡顺序在不同时段分别接受左侧IPS阳极刺激、右侧IPS阳极刺激和假刺激。我们发现，刺激左侧IPS而非右侧IPS或假刺激能提高算术运算速度。这些结果为左侧IPS在广泛算术任务中的功能作用提供了进一步证据，并凸显了非侵入性脑刺激在认知增强方面的潜力。
