Small-molecule drug reactivates dormant nerve pathways; could complement regenerative strategies. Most people with spinal cord injury are paralyzed from the injury site down, even when the cord isn’t completely severed. Why don’t the spared portions of the spinal cord keep working? Researchers at Boston Children’s Hospital now provide insight into why these nerve pathways remain quiet...
