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.
Answers: Don't confuse axons with neurons. There are approximately 100,000,000,000 neurons in the human brain. Most of them are support cells and have nutritive, immunologic and protective functions. The number of axons per cell vary, mostly in the types of cells. For example Purkinje cells have many axons and therefore many more connections.
