Main characteristics
The tDCS is done by putting two electrodes on the scalp and running weak direct current between them so the current passes through the brain. Different areas of the brain can be affected based on the position of the electrodes. Depending on whether the stimulation is anodal or cathodal, the neuronal resting membrane potential is either depolarized or hyperpolarized respectively. Because the neurotransmitters are polar,
