What Is White Matter In The Brain? - Simply Psychology
2023年9月18日 · White matter essentially acts as the brain's communication network, connecting different parts of gray matter and facilitating coordinated brain function. White matter in the brain consists of myelinated axons, which are nerve fibers covered by …
White matter - Wikipedia
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.
