Transcranial direct current stimulation (tDCS)TDCS is a form of neurostimulation that uses a constant, low current delivered directly to the area of the brain of interest via small electrodes. When these electrodes are placed in the area of concern, the current induces current flow in the cerebral cortex, which can increase or decrease neuronal excitability in specific areas to alter brain functioning. |
