The Basic Things You Need To Know About tDCS:   Transcranial Direct-Current Stimulation which is abbreviated as (tDCS) is a type of simulation that is portable and works simultaneously to help deliver an electric current that is low to the scalp, using a neuromodulatory technique. The current applied to the scalp ranges from 1 to 2 mA.   To make sure that the neurons are depolarized respectively, this tDCS was designed to work in such a way that the positive and negative current is applied to an area through electrodes. The rate at which the current flows and the specific location it goes to in the brain is determined by positions of both the anode and cathode electrodes.   Despite being an electric current, the amount of current delivered by the tDCS is negligible. This simply means that it has no potentials of causing any action in the neuron. What the current been supplied which is at a sub-threshold level does is to either reduce or increase the distance bet...
