1. A method of electrically stimulating neural tissue of the brain comprising the steps of:

  • providing a source of electrical pulses;

    providing a first electrode;

    providing an electrical return path;

    connecting the first electrode to the source of electrical pulses;

    placing the first electrode in tissue of a patient'"'"'s brain;

    applying a hyperpolarizing electrical pre-pulse to the tissue through the first electrode wherein the tissue is more susceptible to subsequent electric stimulation;

    applying a subsequent depolarizing electrical pulse to the tissue through the first electrode wherein an action potential is generated in the tissue.
