1. A display system providing visual stimuli to a patient while lying in a horizontal position within a Magnetic Resonance Imaging (MRI) apparatus, said system comprising:

  • a video interface having at least one input and at least one output, said input available for coupling to at least one video device capable of providing an NTSC output;

    at least one projector coupled to said output of said video interface converting said output into a visual image;

    at least one flexible fiber optic image guide coupled to said projector;

    means for coupling said visual image from the output of said projector into a first end of at least one said image guide; and

    facial mounted glasses coupled to a second end of at least one said fiber optic image guide available for positioning directly over each eye providing visual stimuli discernable thereto as transferred through said image guide, said glasses comprising;
