Can the brain grow new neurons?

In the early stages of development, the brain is highly flexible: damage to a specific area can often be repaired because existing neurons (specialized nerve cells that communicate with one another using chemical and electrical signals) can form new connections with other nerve cells. By the end of childhood, however, the brain loses much of this reparative power. While the adult brain can rewire itself to some degree, most of the neurons that die cannot be replaced. Unlike the heart, which can still support a marathon runner after losing 10% of its tissue, a 10% loss in the adult brain can result in devastating disability.
