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 brain’s limited capacity to regenerate triggered the belief that neurogenesis — the birth of new brain cells — ceased after embryonic development. In the latter half of the 20th century, scientists found new cells are born in the brain throughout life. Today this knowledge is helping scientists understand learning and memory.
