Coaxing injured nerve fibers to regenerate by disabling 'brakes' in the system

Expanding on prior research, scientists provide further evidence that regeneration of nerve fibers after brain or spinal cord injury is limited by a lack of response to growth factors induced by the injury. They show in mice that axons can regenerate vigorously when responsiveness is restored genetically -- a finding that could lead to ways of helping people recover from brain or spinal cord injury.
