    The transcranial Direct Current Stimulator is a non-invasive nerve regulation device with the characteristics of portable, non-damage, low-cost, safe and long-acting which is developed and produced independently by Shenzhen Ying-chi Technology CO.,Ltd. It consists of an electrical stimulator, an anode electrode and a cathode electrode. The electrodes are fixed to the scalp and the stimulator can output the weak direct current of 1-2 mA, which causes current to flow from the anode electrode to the cathode electrode. Part of current passes through the skull to affect on the cerebral cortex which can change the resting potential of neuron, regulate the excitability and neurotransmitter secretion of neuron. Thus affect the corresponding sensory perception, motor and cognitive behavior.
