1. An electrode system for coupling neural tissue to an electrical circuit comprising:

  • a. a central spine of an electrically insulating material;

    b. a plurality of semi-rigid fingers of an electrically insulating material orthogonally attached to said central spine and curved about the same radius of curvature as said neural tissue wherein each of said plurality of semi-rigid fingers has an inner surface and wherein each of said plurality of semi-rigid fingers has a length less than a circumference of a circle having said same radius of curvature;

    c. an electrical conductor positioned on said inner surface of a one of said plurality of fingers; and

    d. means electrically coupled to said electrical conductor for electrically coupling said neural tissue to said electrical circuit.
