Fortunately, many of the factors that influence our DNA to produce BDNF factors are under our direct control."

The brain has the ability to regenerate itself, like any other part of the body. Likely includes many parts of the brain and isn't limited to just the brain - also spinal cord and peripheral nervous system.
