white matter tracts

White matter tracts are bundles of nerve fibers in the brain and spinal cord that act like communication highways. They connect different parts of the nervous system, allowing for quick and efficient transfer of information such as sensory data, thoughts, and movements. These tracts are made up of myelinated axons, which are nerve fibers covered with a fatty layer called myelin. This insulation speeds up electrical signals, enabling seamless coordination between various brain regions and the body. In essence, white matter tracts facilitate interconnected functioning and communication within the nervous system.
