Transcranial electrical stimulation (tES) is a non-invasive, brain stimulation treatment that uses electrical currents to stimulate specific parts of the brain. It modulates neuronal activity by delivering weak current (0.5-2mA) through two electrodes placed on the scalp up to 40 minutes. There are two types of stimulation, anodal stimulation acts to excite neuronal activity while cathodal stimulation acts to inhibit it.
