Composed of primarily myelinated axons, the white matter is the "highways and subways of the brain" connecting one region to another and trafficking in and out of the grey matter. In the myelinated nerve fibers, layers of myelin sheaths wrap around each axon to provide protection and insulation to the axon and to allow rapid conduction of action potentials. Myelin establishment and maintenance is considered a crucial requirement for fully functional con- nections between neurons in the central nerve system (CNS).展开更多
