Quick Summary
Researchers at Karolinska Institutet have created the first detailed map showing how genetic activity is controlled in individual cells of the adult human brain and spinal cord. The study, published in Nature Neuroscience, shows that oligodendroglia, the cells that form the brain's insulating myelin, retain an "epigenetic memory" of developmental programs long after these genes are no longer active.
