Oct 12, 2023 · 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. Jul 26, 2017 · The brain is primarily made up of neurons, which send nerve impulses and store information, and various support cells which nurture, insulate, and protect neurons so they can do their jobs reliably.
