White matter area of brain mostly contains myelinated axons (long relays extending out of soma)White matter has a high content of lipid fat which grey matter does not have.Grey matter is fully developed by the time a person is in his or her 20s while white matter develops all through the 20s and peaks in middle age.Grey matter conducts, processes, and sends information to various parts of our bodies while white matter interprets sensory information form different body parts.
