Preferred term

transcranial direct current stimulation  

Definition

  • "tDCS [transcranial direct current stimulation] involves the delivery of weak electrical currents (usually ranging from 1 to 2 mA) to the scalp by means of two electrodes, a positively-charged anode and a negatively-charged cathode. The current is thought to modulate the resting membrane potential of neurons depending on the polarity of the electrode, such that anodal stimulation induces depolarization of the membrane potential and increases cortical excitability, and cathodal stimulation induces hyperpolarization and decreases cortical excitability." (Galli et al., 2019, p. 231).
