Cortical excitability in one hemisphere increased by the use of one anode is often used in studies of transcranial Direct Current Stimulation (tDCS). Cortical areas in both hemispheres may be involved in mental processes. A non-invasive technique for brain simulation is tDCS. Cortical excitability is modulated by a small direct current passing to the scalp. According to recent studies, mood improvements and craving reduction for patients with addictive disorders and substance use may be linked to tDCS. Not only does tDCS help people with disorders, but it may also improve the cognitive abilities of healthy people. The two electrodes used in conventional studies of tDCS are made up of sponge pads, used to deliver current. One active electrode
