That portion of the brain that appears gray. The color reflects the absence of myelination (which makes the tissue appear white). The gray matter consists of the cell bodies, dendrites, and unmyelinated axons that comprise the nervous system's microcircuitry.
Otherwise known as the cerebral cortex, or the "thinking matter" of the brain, it is composed of nerve cells and blood vessels. Growth factors: Substances produced by the body to control growth, division and maturation of cells and tissues.
A segment of the spinal cord that is dominated by the cell bodies of neurons. go to glossary index
Nerve tissue that primarily consists of nerve cell bodies, dendrites, and unmyelinated axons, thus having a gray appearance. In contrast, white matter predominantly contains myelinated nerve fibers.
The butterfly-shaped area, centrally located in the spinal cord, when viewed in cross-section. It contains clusters of nerve-cell bodies.
Gray matter is composed principally of nerve cell bodies and their fibers and glial cells.
The neural tissue made up largely of nerve cell bodies that constitutes the cortex covering the cerebral hemisphere, the nuclei in lower brain areas, columns of the spinal cord, and the ganglia of the autonomic nervous system.
Grayish nerve tissue (especially of the brain and spinal cord). The cerebral cortex–the surface layer of gray tissue of the cerebrum of the brain–is often referred to as gray matter.
Nerve tissue in the brain and spinal cord that contains neuron cell bodies, dendrites, and nonmyelinated axons, and therefore appears gray or non- white in color.
Areas in the central nervous system that are dominated by neuron cell bodies, neuroglia, and unmyelinated axons.
the "thinking brain" appears gray because it is composed of numerous nerve cells and blood vessels. The outer layer of the cerebrum - the cerebral cortex, and areas deep within the brain - the basal ganglia, are made up of gray matter.
greyish nervous tissue containing cell bodies as well as fibers; forms the cerebral cortex consisting of unmyelinated neurons
Portions of the CNS where nerve cell bodies are concentrated. Cortex is gray matter. So are the anterior and posterior horns of the spinal cord and more.
Collections within the central nervous system of nerve cell bodies.
The part of the CNS composed mainly of cell bodies. See White Matter.
the darker-colored tissues of the central nervous system; in the brain, the gray matter includes the cerebral cortex, the thalamus, the basal ganglia, and the outer layers of the cerebellum.
The nerve cell bodies to muscle and sensory outflow and input, respectively.
refers to the tissues of the brain that make up the cortex. Contrast with white matter.
the parts of the brain that contain the cell bodies of nerve cells (neurons).
Portions of the nervous system with a gray color; the gray matter primarily contains the bodies of nerve cells.
Brain tissue consisting mostly of neuronal cell bodies and dendrites; constitutes the outer, extensively folded layer of the brain.
Made up of groups of neuron cell bodies.
Grayish nerve tissue of the brain and spinal cord consisting chiefly of nerve cells.
Term used to describe an area of the brain that is rich in nerve cell bodies.
Dark tissues of the central nervous system, including cerebral cortex, thalamus, basal ganglia, etc.
Those portions of the nervous system consisting primarily of nerve-cell bodies which are gray-colored. Particularly, certain areas of the brain, such as the cerebral cortex. In the Cayce readings, the gray matter of the nervous system is associated with "activity." (See impulse and activity.)
central nervous tissue that is relatively dark in color (in contrast to white matter) because of the relatively high proportion of nerve cell nuclei present
Gray Matter is a short horror sci-fi story by Stephen King, first published in Cavalier in October 1973. It was re-published in his Night Shift collection in 1978 and again in Arbour House Necropolis in 1982. It is set in the same area as King's novel Dreamcatcher.
Gray Matter was a hardcore punk band from Washington, D.C., who played in the 1980s and 90s. They disbanded in 1986, but reformed in 1990.
