A recent study conducted by researchers at Sweden's Karolinska Institutet has provided strong evidence that the adult human brain continues to generate new neurons well into late adulthood, including individuals up to 78 years old. This neurogenesis occurs primarily in the hippocampus, the brain region responsible for memory and learning. The findings overturn the long-held belief that neuron production ceases after childhood and suggest potential new avenues for therapies targeting neurological and psychiatric disorders. The research utilized RNA sequencing and post-mortem examination of hippocampal tissue spanning infancy to old age to identify neural progenitor cells and confirm ongoing neurogenesis. This discovery resolves a decades-long scientific debate and highlights the brain's adaptability throughout life.
