Every cell in a human brain contains the same sequence of DNA, but in different cell types different genes are copied onto strands of RNA for use as protein blueprints. This ultimate variation in which proteins are found in which cells—and at what levels—allows the vast diversity in types of brain cells and the complexity of the brain.The Other Brain Cells. The structures within the brain are made up of about 100 billion neurons, as well as trillions of support cells called glia. Neurons may be the more important cells in the brain that relay messages about what you're thinking, feeling, or doing.
