Transcranial direct current stimulation - update 2011.

Non-invasive brain stimulation with weak direct currents (transcranial direct current stimulation (tDCS)) has emerged as one of the major tools to induce neuroplastic cortical excitability alterations in humans since its (re-) introduction to the arsenal of plasticity-inducing brain stimulation tools. In this review, we gather newly emerged knowledge about the effect of tDCS on brain function in both, basic and applied research. This overview will deliver an update of the last two years of research, because especially during this time numerous important studies were published covering the above-mentioned fields.
