Many...Nov 30, 2022 · Neurons are associated with support cells called glia. Neuroscientists have long believed that glia outnumber neurons by 10:1 (or more). However, recent investigations suggest that in some regions of the brains of humans and other primates, that ratio is closer to 1:1. However, the ratio of glia to neuron from region to region varies considerably. 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.
