Methods are provided to reliably identify and surgically eradicate aberrant DREZ in patients suffering from spinal cord injury. The methods include identifying potential aberrant DREZ using a combination of mapping techniques based on the location of the patients perceived pain, analysis of the spontaneous electrical hyperactivity in targeted DREZ, and analysis of evoked transcutaneous C-fiber stimulation both in pre-operative and operative conditions. Methods are also provided for identifying potential pain effecters in aberrant DREZ, useful in the preparation of non-invasive therapeutics for central pain characteristic of spinal cord injury.
