Brain Glucose Levels Act as a Metabolic Switch for Myelin Formation

Scientists have long known that myelin doesn’t appear everywhere in the brain at once. Some regions myelinate early, others much later, shaping motor development and cognitive maturation. A new study in Nature Neuroscience reveals that shifting glucose levels act as a metabolic switch, directing progenitor cells when to divide and when to mature into myelin-forming oligodendrocytes.
