Finding a Cure for Spinal Cord Injury
Traumatic injury to the central nervous system (CNS) usually results in irreversible loss of function. Consequently, individuals with injured spinal cords can be permanently paralyzed. This function loss occurs because of the death of nerve cells and their support cells as well as the severing of very long processes that transmit electrical signals from one nerve cell to others. Transected CNS axons do not re-grow or reestablish connections with their targets.
