The brain is the most important organ in the body. This soft, warm piece of flesh allows you to think, walk, talk, learn, make friends, have emotions, and know what it means to be alive!

Although it weighs just two and a half pounds and is approximately 75 percent water, the functioning of every system of the human body is entirely dependant upon the brain. Yet when it comes to health, people rarely think of the brain, even though it is the "master organ" of the human body.

In this powerful special presentation, Gary Null PhD and the world's top brain experts will take you on a journey of the most fascinating machine in the universe.
