Damaged central-nervous-system cells may not regrow readily, but the ones that survive a trauma can become more efficient, changing what is known as their central state of excitability--or the threshold at which even a sputtering signal can send them into action. "I don't think any scientist would dispute that a younger body is more plastic in this...

But when they landed in the sickened brain tissue, they appeared to know to go to work, restoring the enzyme that the babies lacked and causing affected nerve cells to regrow myelin insulation and healthy ones to keep what they had.

McDonald has conducted studies with spine-injured rats in which some of the animals are given no therapy after injury and others are given exercise. When their cords are later examined, the stimulated animals show new cell growth at the site of the lesion. "We believe," says McDonald, "that we can induce selective and robust cell growth...
