Since its initial discovery in the 1800s until recently, myelin was considered a simple insulator for axons, and its formation was believed to be regulated by predetermined biochemical and cellular processes. Moreover, both oligodendrocytes and the myelin they generate were considered to be static components of the nervous system. However, recent studies have revealed that oligodendrocyte development and myelination are highly dynamic processes that continue throughout adult life, are influenced by experience and neuronal activity, and contribute to cognitive function and behavior
