Long-term survival of anucleate axons and its implications for nerve regeneration.

abstract：:Imagine the decisions you might make while playing a simple game like 'matching pennies'. At each play, you and your opponent, say the mathematician John vonNeumann, each lay down a penny heads or tails up. If both pennies show the same side, vonNeumann wins, if not, you win. Before each play, you have the subjective ...
