走神是一种认知过程，在这个过程中，人们自发地产生与他们当前活动无关的想法。当人们受到消极情绪的影响时，走神的想法类型与情绪障碍相关的想法相似（例如，对过去的负面想法）。经颅直流电刺激（tDCS）是一种非侵入性脑刺激，可以调节健康和临床人群的认知和影响。90名参与者接受了兴奋性，抑制性或假tDCS到默认模式网络（DMN）的双侧下顶叶（IPL）节点，以评估批评后适应不良思维游荡的变化。tDCS在听到批评后并没有改变走神的频率，但它确实改变了人们走神的内容。具体来说，阴极刺激降低了对过去的负面走神的频率。未来的研究可能会调查DMN区域的tDCS，作为对患有负面，过去导向认知的情绪障碍患者的干预。
Mind-wandering is a cognitive process in which people spontaneously have thoughts that are unrelated to their current activities. The types of mind-wandering thoughts that people have when affected by a negative mood resemble thoughts associated with mood disorders (e.g., negative thoughts about the past). Transcranial direct current stimulation (tDCS) is a form of noninvasive brain stimulation that can modulate cognition and affect in healthy and clinical populations. Ninety participants received either excitatory, inhibitory, or sham tDCS to bilateral inferior parietal lobe (IPL) nodes of the default mode network (DMN) to assess changes in maladaptive mind-wandering following criticism. tDCS did not change mind-wandering frequency after hearing criticism, but it did change what people mind-wandered about. Specifically, cathodal stimulation decreased the frequency of negative mind-wandering thoughts about the past. Future studies could investigate tDCS of DMN regions as an intervention for patients with mood disorders who suffer from negative, past-oriented cognitions.
