经颅直流电刺激是一种无创性大脑皮层刺激方法。本文简要回顾其起源和发展，着重综述其机制。目前观点认为，经颅直流电刺激可能通过改变皮层兴奋性、增加突触可塑性、影响皮质兴奋/抑制平衡、改变局部脑血流、调节局部皮层和脑网联系等途径发挥调节脑功能的作用。本文通过比较分析相关文献、总结研究结果，提出要取得理想的刺激效果，仍有待深入探讨的两个问题，即刺激参数的选择及经颅直流电刺激与任务执行的时间关系。

Transcranial direct current stimulation is one of the non-invasive brain-stimulation techniques. Based on the introduction of the origin and development, this article gave an overview of the mechanisms emphatically, the current view is that the transcranial direct cur-rent stimulation may exert effect on neuromodulation by changing cortical excitability, increasing synaptic plasticity, impacting cortical exci-tation/inhibition balance, altering regional cerebral blood flow, modulating the activity within and between different cortical networks. In this review, clinical studies and analysis findings were compared, and then 2 problems should be discussed for ideal effects:choice of stimu-lating parameters and timing of the stimulation in relation to task performance.
