Rick Hanson talks about using your mind to change the brain.

Knowing the mind shapes the mind. A degree of self-awareness is necessary if you wish to change your brain. Essentially, this is a way to alter your way of thinking. Reduce the negative and grow the positive. As you change your way of thinking, you will realize that there is not much room for negative thoughts if you wish to cultivate your mind. You have to plant the seed of positivity and happiness and let it grow in your mind. This hard-wiring of happiness is aided by Rick Hanson through a guided meditation that will help the positive thoughts flow freely and continuously that will help your mind change your brain.
