Transcranial Direct Current Stimulation (tDCS): A Beginner’s Guide for Neuroergonomists

Abstract

This Beginner’s Guide is intended to provide the necessary information for neuroergonomists to be able to understand the effects and usages of Transcranial Direct Current Stimulation (tDCS) on the brain. A thorough timeline provides the transformation of tDCS with technological advancements as well as a representation of its benefits throughout human history. It was these benefits that propelled tDCS to still be a modern-day solution to neuroergonomical problems. A large part of this chapter is dedicated to the impacts of tDCS, specifically, its effects on motor and cognitive functions and how the configurations of a session can alter the intended results. By the end of this guide, the reader should have a comprehensive understanding of what tDCS is, how it works, how to accurately design and implement tDCS configurations as well as the impacts it has on cognitive and motor functions of the brain.
