It is named after its distinctive brownish-gray color, in contrast with white matter, another type of neural tissue which appears white because it is coated in myelin sheathes.
1 Gray matter located on the surface of the brain is called cortex (e.g., cortex of the cerebral hemispheres, cortex of the cerebellum). 2  Masses of gray matter located deeper in the brain are called nuclei .(e.g., brainstem nuclei, nuclei of the thalamus).yramidal cells are the efferent (long-axon) cells of the cerebral cortex. The name refers to the shape of the cell body as seen in standard sections perpendicular to the cortical surface. The apex of the pyramid points toward the cortical surface.
