Brain, brainstem, and spinal cord sections showing gray and white matter. All levels of the central nervous system have a combination of gray matter and
white matter. Gray matter is composed of the neurons and the supporting cells, along with the connections between neurons. The gray matter is where the
information processing of the brain occurs. White matter is composed of axons carrying information between parts of the nervous system. In the cerebral
hemispheres, there is white matter in the middle forming connections, and gray matter at the surface and in nuclei within the brain. In the brainstem and
spinal cord, there is white matter on the outside, and gray matter within. (Part B: Used with permission of John A. Buford, PT, PhD. Part C: Adapted with
