1. A method of reducing pain sensations resulting from the propagation of body-generated action potentials towards the central nervous system through small-diameter sensory fibers in a nerve bundle, without unduly reducing other sensations resulting from the propagation of body-generated action potentials towards the central nervous system through large-diameter sensory fibers in said nerve bundle, comprising:

  • applying to said nerve bundle at least one electrode device capable, upon actuation, of generating unidirectional action potentials to be propagated through both the small-diameter and large-diameter sensory fibers in said nerve bundle away from said central nervous system; and

    actuating said electrode device to generate said unidirectional action potentials to produce collision blocks with respect to said body-generated action potentials propagated through said small-diameter fibers.
