Adult Brains Form New Neurons Even at 78, Rewriting Neurogenesis Rules

A 2025 study from Karolinska Institutet provides direct evidence that the adult human hippocampus can generate new neurons, identifying dividing progenitor cells in the dentate gyrus of individuals up to age 78 using single-nucleus RNA sequencing. This supports ongoing adult neurogenesis in at least one brain region, though there is wide individual variation and it does not imply broad brain rejuvenation or immediate therapies; replication is needed to confirm findings and understand drivers of variability.

Adult Human Brains Continue to Generate New Memory Neurons

A new study confirms that the human hippocampus continues to generate new neurons throughout adulthood, particularly in the dentate gyrus, which is crucial for memory and emotion regulation. Using RNA analysis and machine learning, researchers found ongoing neurogenesis across different ages, with potential implications for understanding brain aging, learning, and treating neurodegenerative diseases.

Study Confirms Adult Brain Continues to Generate New Neurons

Recent research from Sweden demonstrates that adult human brains continue to generate new neurons, particularly in the hippocampus, challenging the long-held belief that brain cell growth stops after childhood. The study analyzed over 400,000 individual cell nuclei, finding neural progenitor cells actively dividing in adults, which could have implications for treating neurological conditions and understanding brain plasticity. However, the extent and pattern of neurogenesis vary among individuals, raising further questions about its role in health and disease.

Adults' Brain Cell Growth: Is It Possible?

Research suggests that adults may be capable of growing new brain cells, particularly in the hippocampus, although some scientists remain skeptical due to limitations in current measurement methods and conflicting evidence. The possibility of adult neurogenesis has significant implications for brain plasticity and potential therapies for brain injuries and neurodegenerative diseases.
