New Neurons Form in the Hippocampus Even in Late Adulthood
- Researchers led by Jonas Frisén at Karolinska Institutet published a July 3, 2025, Science paper showing new neurons form in the hippocampus of people aged 0 to 78 years.
- This study addresses a long debate since past views held that humans stop making neurons after childhood, though animal studies have shown lifelong neurogenesis since the 1960s.
- The team analyzed over 400,000 hippocampus cell nuclei from 24 people and used machine learning trained on childhood data to identify progenitor cells in adult samples.
- Marta Paterlini expressed strong confidence in their findings, while Dr. W. Taylor Kimberly highlighted the impressive achievement of identifying rare new neurons in the adult brain, thereby supporting the existence of active adult neurogenesis.
- These findings suggest adult neurogenesis may enhance understanding of brain plasticity and could inform regenerative therapies for neurological diseases like Alzheimer's.
