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.
The cells of the brain include neurons and supportive glial cells. There are more than 86 billion neurons in the brain and a more or less equal number of other cells. Brain activity is made possible by the interconnections of neurons that are linked together to reach their targets.
