Science Discovers That the Brain Regenerates Even in Adulthood
For decades, it was assumed that once adulthood was reached, the human brain could no longer produce new neurons.
Today, a discovery by a team of scientists from the Karolinska Institutet has debunked this myth through a scientific study.
Thanks to single-nucleus RNA sequencing and an artificial intelligence algorithm, the researchers demonstrated that progenitor cells and immature neurons exist in the hippocampus from early childhood up to the age of 78. This new neuronal growth, also known as neurogenesis, occurs in the dentate gyrus of the hippocampus—a fundamental part of the brain involved in learning, memory, and emotions. It is here that incoming information from the cortex is processed and transformed into memory traces.
These scientists studied nearly half a million nuclei fr...
