What is tDCS?
Transcranial Direct Current Stimulation (tDCS) is a non-invasive neurostimulation treatment that uses the application of a low electrical current to modify neuronal activity. Powered by a small battery, a low level of current is passed through two electrodes placed on the head over a targeted area of the brain. An electrical pathway forms between the electrodes and the brain, causing neurons in that area to become more likely to respond to neural electrical signals. This neuronal activity can be sustained and can have a therapeutic effect on brain function. Depending on the brain area being stimulated, studies have suggested that tDCS can be used for improving behaviour, cognitive performances, and/or mood. tDCS holds great potential as a tool for therapy and research because it has fewer side effects than other neurostimulation therapies; is portable, user-friendly and cost-effective.
