Transcranial direct current stimulation - tDCS [brmlab] Transcranial direct current stimulation is a type of nonivasive cortical modulations technique witch use low DC current in order 25-80uA/cm2(more in HD-tdcs) via skalp electrodes to change resitng potentials of neurones.This chanages depend of polarity of stimulation = orintation od el. field to the neurones,the anodal (+) stimulation increases the neuronal excitability and Cathodal (-) neuronal excitability.When positive stimulation causes a depolarization of the resting membrane potential, which increases neuronal excitability and allows for more spontaneous cell firing.

When negative stimulation is delivered, the current causes a hyperpolarization of the resting membrane potential. Safety considerations for tDCS this part only shows various factors influencing the effect in end you must consider all this factors at once with all its concetivity and dependences.
