Methods are disclosed of preparing neural tissue of the brain for subsequent electrical stimulation. For example, first, second and third electrodes may be placed in close proximity to tissue of a patient's brain. A hyperpolarizing electrical pre-pulse may be applied to the tissue through the first electrode wherein the tissue is more susceptible to subsequent electric stimulation, or a depolarizing electrical pre-pulse may be applied to the tissue through the first electrode wherein the tissue is less susceptible to subsequent electric stimulation. Other exemplary embodiments are also disclosed. |
