tDCS (see Glossary) offers a non-invasive means by which to establish causal relationships between circumscribed regions of the brain and their underlying perceptual, cognitive, and motor functions (Box 1). To date, tDCS has been used to alter performance across a range of cognitive tasks [1,2] (Table 1), and has been trialled as a treatment for a variety of psychiatric and neurological conditions [3,4], including depression [3,5], stroke [4], and altered states of consciousness [6]. Recently there has been debate in the popular media over the use of tDCS to enhance performance and augment gains from cognitive training [7–12].
