What is tDCS and how does tDCS work. Transcranial Direct Current Stimulation (tDCS) is a form of non-invasive neurostimulation that delivers a constant low level current to the brain through the use of electrodes typically placed on the scalp. This neuromodulation technique uses a steady current between 1 - 2 mA delivered through electrodes to targeted regions of the brain to modulate brain function. Using different electrode configurations, tDCS can be used to either excite or inhibit neuronal activity in the targeted region. • The positioning of the electrodes is used to determine the flow of current through different regions of the brain. These different electrode placements are called montages. Depending on the montage used, different regions of the brain are targeted to elicit the various desired effects. Unlike transcranial magnetic stimulation (TMS), the current used in tDCS is not strong enough to trigger an action potential but rather effects the neurons resting membrane potential. When applying anodal (positive) stimulation, the electrode is used to facilitate depolarization of the neurons resulting in excitatory stimulation. Conversely, during cathodal (negative) stimulation, the electrode is used to induce hyper-polarization of the neurons resulting in inhibitory stimulation. Conventional tDCS montages use two electrodes: the Anode electrode and the Cathode electrode. The Anode electrode has a positive voltage relative to the Cathode electrode. Current enters the body under the Anode electrode, flows through the brain, and exits the body at the Cathode electrode. By controlling the position of the anode and cathode electrode, the current flow through the brain can be targeted. • To try tDCS or learn more, visit www.caputron.com • Best tDCS Devices of 2020: https://caputron.com/pages/best-tdcs-... • What is tDCS: https://caputron.com/pages/what-is-tdcs • Follow us on Twitter! • / caputron • Like us on Facebook! • / caputron • Disclaimer: This content is not intended to be a substitute for professional medical advice, diagnosis or treatment.
