Транскраниальная электрическая стимуляция: возможности и ограничения
Transcranial electrical stimulation (TES) is a group of noninvasive brain stimulation methods that apply weak electric currents through the scalp to interfere with brain activity. TES methods include transcranial direct current stimulation (tDCS), transcranial alternating current stimulation (tACS) and transcranial random noise stimulation (tRNS). These methods are prominent in contemporary cognitive neuroscience, but the specific mechanisms of TES neuromodulation are still unclear. This review is devoted to the history of TES, the most established effects of TES, as well as the possibilities and limitations of TES applications for research in cognitive neuroscience, for neurorehabilitation and treatment of neurological and psychiatric disorders, and for cognitive enhancement in healthy people.
