- Some rare neurons can reconnect parts of the spinal cord.
- Spinal cord injury breaks the bundle of nerve signals.
- This break often causes lasting paralysis and health problems.
- Researchers put neural stem cells into the injured cord.
- A small group of transplanted neurons join walking circuits.
- When scientists activate these neurons, leg muscles respond.
- Some animals later showed muscle reactions.
- Transplanted neurons are young and must learn to work.
- Future therapies may combine cells with activity training.
