Abstract
The most frequently used low-intensity transcranial electrical stimulation (tES) techniques are transcranial direct current (tDCS), alternating current (tACS), and random noise stimulation (tRNS). During tES, currents are applied with intensities ranging between 0.4 and 2 mA through the human scalp. It has been suggested that tACS interacts with cortical oscillations in a frequency-specific manner at single and using tRNS, at multiple frequencies. All techniques might affect homeostatic mechanisms or the signal- to-noise ratio in the brain. The aim of this review is to summarize basic aspects of tACS and tRNS, their possible neuronal mechanisms and clinical applications.
