Gray matter: The cortex of the brain, which contains nerve cell bodies. The gray matter is so named because it is darker than the white matter, the part of the brain that contains myelinated nerve fibers. Last Editorial Review: 3/19/2012. Back to MedTerms online medical dictionary A-Z List.
Grey matter is distinguished from white matter, in that grey matter contains numerous cell bodies and relatively few myelinated axons, while white matter is composed chiefly of long-range myelinated axon tracts and contains relatively very few cell bodies.The color difference arises mainly from the whiteness of myelin.rey matter contains most of the brain's neuronal cell bodies. The grey matter includes regions of the brain involved in muscle control, and sensory perception such as seeing and hearing, memory, emotions, speech, decision making, and self-control.
