The Difference Between Grey Matter and White Matter. We’re used to thinking of the brain as a single organ; however, it is made so many sub-structures that sometimes I consider it it’s own organ system. The two largest major subdivisions of the brain are gray (grey) matter and white matter. in this video I'm going to talk about gray and white matter in the central nervous system which is mostly the brain and the spinal cord there are areas called grey matter grey matter that contain most of the neuron somas so most of the neuron somas in the central nervous system are found in the gray matter and then there are other areas called white matter and in the white matter of the 2012-02-18 · Grey matter contains neural cell bodies, in contrast to white matter, which does not and mostly contains myelinated axon tracts. The color difference arises mainly from the whiteness of myelin. In living tissue, grey matter actually has a grey-brown color which comes from capillary blood vessels and neuronal cell bodies. There are well-documented differences in the neurochemical response to ischemia of the white matter (WM) compared with gray matter (GM) compartments of brain.

The white matter refers to those parts of the brain and spinal cord that are responsible for communication between the various gray matter regions and between the gray matter and the rest of the body. Gray matter are cell bodies, white matter are myelinated fiber tracts.

Grey matter occupies 40 percent of the brain, while white matter fills 60 percent of the brain. 4. Grey matter has a grey color because of the grey nuclei that comprises the cells. Overall, gray matter occupies 40 percent of the cerebrum, while white matter fills the remaining 60 percent. White matter lies beneath the gray matter and is composed of long nerve fibers insulated by myelin sheaths. Not only does myelin give white matter its distinctive color, but it also helps to speed electrical signals along nerve axons. The outside of the spinal cord is composed of large white matter tracts.

It is formed by the bundles of both myelinated and unmyelinated fibers, but predominantly the myelinated fibers. Anterior median fissure and posterior median septum divide the entire mass of white matter into two lateral halves. Background and Purpose— Although gray matter (GM) and white matter (WM) have differing neurochemical responses to ischemia in animal models, it is unclear whether this translates into differing thresholds for infarction. We studied this issue in ischemic stroke patients using magnetic resonance (MR) techniques.

White matter actually dominates, at about 60%.
