Brain work like a computer. It is easier to understand the brain. White matter is the substance that connects all the matter and transmits the message. This is the nerve tissue in the brain that contains nerve fibers. The fibers connect the nerve fibers and these nerve fibers are covered by a myelin sheath.
Myelin sheath help in improving the speed of information from one neuron to another neuron. The myelin speeds up the signal between cells and the signal cells which sends and receives cells.
