Transcranial electrical stimulation (tES) mechanisms and its effects on cortical excitability and connectivity

AbstractIn this review, we describe transcranial electrical stimulation (tES) techniques currently being used in neuroscientific research, including transcranial direct  current (tDCS), alternating current (tACS) and random noise (tRNS) stimulation techniques. We explain how these techniques are used and summarise the proposed mechanisms of action for each technique. We continue by describing how each method has been used to alter endogenous neuronal oscillations and connectivity between brain regions, and we conclude by highlighting the varying effects of stimulation and discussing the future direction of these stimulation techniques in research.
