White matter is tissue in the brain composed of nerve fibers. The fibers (called axons) connect nerve cells and are covered by myelin (a type of fat). The myelin is what gives white matter its white color. Myelin speeds up the signals between the cells, enabling the brain cells to quickly send and receive messages.
