One of the most interesting bits of research that I have come across lately comes from the Proceedings of the National Academy of Sciences.  The paper is entitled, Running Enhances Neurogenesis, Learning, and Long-term Potentiation.  You may be like me.  I was taught that once brain cells die, they’re gone.  We know now that brain cells can regenerate, a process called neurogenesis.  What is interesting is that running causes this to take place in a part of the brain responsible for long-term learning.  How cool is that?  Your brain can become more efficient by running.
