These axons connect the neurons of the brain and spinal cord and The white matter is the substance of the brain and spinal cord that contains the fiber tracts of neuronal axons in the central nervous system.

Both white matter and gray matter are terms that relate with the cells of the brain. A cross section of a brain will show these cells in their respective colours, and they are so named as white and gray matter. If the nervous system were a computer network, gray matter – a non-myelinated portion that contains nerve cells and capillaries – would be the computers and white matter the cables.
