Detection and Assessment of Spinal Cord Injury Using Spectral Coherence

Graded spinal cord injury was induced in rats using the NY-Impactor. Somatosensory evoked potentials (SEPs), in response to stimuli to the nerves in the limbs, were recorded from the cranium. These signals were analyzed using spectral coherence analysis. Results obtained from 15 rats show information that was missed when other techniques are used.
