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 brain is made out of cells. It is a long and very distinguished group of cellsâabout 550 million years or so old. These cells have a small mass. Our brain is about one-and-a-half liters, or three pounds, but it has 1010 cells, which is a huge number of cells. Ten billion cells.
