A recent high-impact study leveraging innovative techniques unveils direct evidence of neural precursor cells and newborn neurons in adult human hippocampi, including in individuals up to age 78. This discovery resolves decades of controversy on human adult neurogenesis. By identifying neural precursor and immature neuron populations, the research confirms ongoing brain cell generation beyond development. Insights from Karolinska Institute and collaborators open new avenues for neurological disease therapies and cognitive aging research.
