1. A near infrared spectrophotometric sensor for non-invasive monitoring of blood oxygenation levels in a subject'"'"'s spinal cord tissue and spinal cord blood vessels, said sensor comprising:

  • at least one light source operative to emit near infrared light signals of a plurality of different wavelengths;

    at least one light detector operative to sense light signals emitted from the light source and passed through the subject'"'"'s spinal tissue, and produce a sensor signal representative of the sensed light signals;

    wherein the light source is separated from the light detector by a distance representative of a distance from a first vertebrae structure of a human spine to a second vertebrae structure of the human spine, to permit alignment of the light source and detector with the first and second vertebrae structure.
