What Is White Matter In The Brain? - Simply Psychology
2023年9月18日 · White matter, comprising about half of the brain, consists of bundles of myelinated axons (nerve fibers). Located in the deeper parts of the brain, white matter acts as the brain’s communication network, connecting different areas of grey matter and facilitating coordinated brain function.
White matter - Wikipedia
Function. White matter is the tissue through which messages pass between different areas of grey matter within the central nervous system. The white matter is white because of the fatty substance (myelin) that surrounds the nerve fibers (axons). This myelin is found in almost all long nerve fibers, and acts as an electrical insulation.
