Here are the facts: Most estimates say we have about 100 billion brain cells (neurons), and about ten times that many, or one trillion, support cells (glia) that help the neurons. We'll just concentrate on the neurons themselves. The brain weighs about 3 pounds, and after age 20, you lose about a gram of brain mass per year.
This knowledge is essential to understanding how you can keep your brain healthy, and why these different strategies work. The 86 billion neurons in your head are constantly active. Even though the brain doesn't account for much of your body weight, it uses 20% of your body's energy to function.It's a matter of gray and white. Gray matter, which contains the parts of neurons that carry out thought processing, uses most of this energy.he 86 billion neurons in your head are constantly active.
