According to Johns Hopkins Medical Center, transcranial direct current stimulation (tDCS), is a non-invasive, painless brain stimulation treatment that uses direct electrical currents to stimulate specific parts of the brain. A constant, low intensity current is passed through two electrodes placed over the head which modulates neuronal activity. There are two types of stimulation with tDCS: anodal and cathodal stimulation. Anodal stimulation acts to excite neuronal activity while cathodal stimulation inhibits or reduces neuronal activity.

Studies from universities worldwide suggest that tDCS (transcranial direct current stimulation) can improve memory, help you learn new information faster, enhance problem solving skills and increase hand-eye coordination response times. MORE tDCS info and FAQs.
