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.
gray areas of brain and spinal cord made up primarily of cell bodies and dendrites of nerve cells rather than myelinated axons. White matter or substance is the tissue composed primarily of myelinated, or medullated, fibers. The bodies of the nerve cells are centered in the gray matter. In the brain the gray matter may be external to white matter, e.g. cerebellum, or central to it, e.g. cerebrum. The cerebral cortex is composed of gray matter and there are some deep-seated nuclei too.
