White matter of the brain
Information
The white matter of the brain contains nerve fibers. Many of these nerve fibers (axons) are surrounded by substance called myelin. The myelin gives the whitish appearance to the white matter. Myelin acts as an insulator, and it increases the speed of transmission of all nerve signals.
