Can adults grow new brain cells?

Scientists are debating whether adults can grow new brain cells, a process called neurogenesis. While studies in animals show new neurons forming throughout life, evidence in humans is limited and controversial. Some researchers claim to have found signs of adult neurogenesis using various techniques, including radiocarbon dating and protein markers. Others remain skeptical, citing potential methodological issues. Understanding adult neurogenesis could have significant implications for treating brain injuries and neurodegenerative disorders, regardless of which side of the debate proves correct.
