"Nerve cells have been growing for hundreds of millions of years. Their navigation system is more precise than any navigation system we've designed. Don't decide where they should go; instead, ask them where they want to go and create conditions that allow them to go there. You're not leading the way, they're recognizing the way. You're just removing the stones that block the path. Similarly, why can't nerve cells undergo original cell repair while bones can? Have you considered this problem from a deeper logical level?"
This conversation changed Manstein's research direction for the next few years.
