非侵入性脑刺激方法正在成为认知科学家工具包中越来越常见的工具。特别是，经颅直流电刺激（tDCS）作为一种因果操纵大脑和了解信息如何处理的工具，显示出很大的前景。这种大脑刺激方法的流行是基于这样一个事实：它安全，便宜，效果持久，你可以增加神经元在一个电极附近放电的可能性，减少神经元在另一个电极附近放电的可能性。然而，这种操纵大脑进行因果推理的方法并非没有复杂性。由于tDCS方法仍在不断完善，尚未标准化，因此文献中的报告显示出一些惊人的不一致性。该技术的主要并发症是tDCS方法使用两个或更多个电极来传递电流，所有这些电极都会对它们下面的组织产生影响。在本教程中，我们将分享我们所学到的关于使用tDCS来操纵大脑如何感知，注意，记忆和响应来自我们环境的信息的知识。我们的目标是为tDCS的新用户提供一个起点，并促进对提高可复制性的方法标准化的讨论。
Noninvasive brain stimulation methods are becoming increasingly common tools in the kit of the cognitive scientist. In particular, transcranial direct-current stimulation (tDCS) is showing great promise as a tool to causally manipulate the brain and understand how information is processed. The popularity of this method of brain stimulation is based on the fact that it is safe, inexpensive, its effects are long lasting, and you can increase the likelihood that neurons will fire near one electrode and decrease the likelihood that neurons will fire near another. However, this method of manipulating the brain to draw causal inferences is not without complication. Because tDCS methods continue to be refined and are not yet standardized, there are reports in the literature that show some striking inconsistencies. Primary among the complications of the technique is that the tDCS method uses two or more electrodes to pass current and all of these electrodes will have effects on the tissue underneath them. In this tutorial, we will share what we have learned about using tDCS to manipulate how the brain perceives, attends, remembers, and responds to information from our environment. Our goal is to provide a starting point for new users of tDCS and spur discussion of the standardization of methods to enhance replicability.
