Damaged nerve cells regenerate.

In Brain Injury, Brain Science by Brainy Days Ahead

Injuries to the spinal cord can cause paralysis and other permanent disabilities because severed nerve fibers do not regrow. In this remarkable breakthrough, scientists at the German Center for Neurodegenerative Diseases (DZNE) have succeeded in releasing a “molecular brake” that prevents the regeneration of nerve connections. Researchers treat mice with a drug that acts upon this growth- inhibiting mechanism. The treatment removed the natural impediment and caused the damaged nerve connections to regenerate.
