Why the White Brain Matters White matter is a vast, intertwining system of neural connections that join all four lobes of the brain (frontal, temporal, parietal, and occipital), and the brain’s emotion center in the limbic system, into the complex brain maps being worked out by neuroscientists.

- Top 10 amazing movie makeup transformations. Gray matter or grey matter is a type of neural tissue which is found in the brain and spinal cord. 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.

White matter disorders - Introduction Gray and white matter. The brain of humans consists of gray matter and white matter. The gray matter contains the nerve cells. White matter-myelin. The white matter of the brain is composed of nerve fibers and myelin. The nerve fibers form the connections between the nerve cells. Myelin is a fatty sheath wrapped around nerve fibers. The myelin sheath has two functions: insulation and acceleration of impulse conduction.

What does white matter on the brain mean? Answers. Best Answer: white matter tansert information from the brain to the spinal cord. sometimes youll hear men have more grey matter and women have more white matter. its the signals your brain sends.ubmit. · just now. Report Abuse. White matter is brain tissue that carries information between the nerve cells in the brain and spinal cord. When white matter doesn’t develop the way it should, or is somehow damaged, the result can be mental retardation and developmental disabilities.

What is Grey Matter? White matter, on the other hand, is mainly composed of long-range myelinated axons (that transmit signals to the grey matter) and very few neuronal cell bodies. Myelin forms a protective coating around these axons, insulating them and improving their transmission of neuronal signals.he grey matter is mainly composed of neuronal cell bodies and unmyelinated axons. Axons are the processes that extend from neuronal cell bodies, carrying signals between those bodies. In the grey matter, these axons are mainly unmyelinated, meaning they are not covered by a whitish-colored, fatty protein called myelin.

Grey matter Grey matter contains most of the brain's neuronal cell bodies. The grey matter includes regions of the brain involved in muscle control, and sensory perception such as seeing and hearing, memory, emotions, speech, decision making, and self-control. The grey matter in the spinal cord is split into three grey columns.

White matter White matter. White matter is composed of bundles of myelinated axons, which connect various gray matter areas (the locations of nerve cell bodies) of the brain to each other, and carry nerve impulses between neurons.

gray matter 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.

- In section, myelin is white whereas the gray matter is that color due to all the gray nuclei contained in the cells that make it up. The white matter is found in the inner layer of the cortex, the optic nerves, the central and lower areas of the brain or brainstem, and surrounding the central shaft of gray matter in the spinal cord.

Difference Between White Matter and Gray Matter Difference Between White Matter and Gray Matter. Both white matter and gray matter are terms that relate with the cells of the brain. A cross section of a brain will show these cells in their respective colours, and they are so named as white and gray matter.

White matter The other main component of the brain is grey matter (actually pinkish tan due to blood capillaries), which is composed of neurons. The substantia nigra is a third colored component found in the brain that appears darker due to higher levels of melanin in dopaminergic neurons than its nearby areas.

What Is White Matter Disease? White matter disease is the wearing away of tissue in the largest and deepest part of your brain due to aging. This tissue contains millions of nerve fibers, or axons, that connect other parts of the brain and spinal cord and signal your nerves to talk to one another. A fatty material called myelin protects the fibers and gives white matter its color.

The Four Cerebral Cortex Lobes of the Brain Cerebral Cortex Lobes. The cerebral cortex is the layer of the brain often referred to as gray matter. The cortex (thin layer of tissue) is gray because nerves in this area lack the insulation that makes most other parts of the brain appear to be white. The cortex covers the outer portion (1.5mm to 5mm) of the cerebrum and cerebellum.

Grey matter or gray matter is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil (dendrites and myelinated as well as unmyelinated axons), glial cells (astroglia and oligodendrocytes), synapses, and capillaries.

White matter disease exacts heavy toll, increasing risk of stroke, Alzheimer's, dementia Unlike Alzheimer's disease, which shrinks the hippocampus causing progressive memory loss, white matter disease is a more diffuse mind-robbing condition that targets small blood vessels deep within the brain's white matter. The disease hardens the tiny arteries, gradually restricting nutrients to white matter -- the connections between brain regions involved in executive abilities such as planning, organizing, problem-solving, and attention.

White matter White matter is a component of the central nervous system, in the brain and superficial spinal cord, and consists mostly of glial cells and myelinated axons that transmit signals from one region of the cerebrum to another and between the cerebrum and lower brain centers.hite matter tissue of the freshly cut brain appears pinkish white to the naked eye because myelin is composed largely of lipid tissue veined with capillaries. Its white color in prepared specimens is due to its usual preservation in formaldehyde.

Cerebellum The white matter of the brain is located in the central and subcortical regions of the cerebral and cerebellar hemispheres and accounts for about 60 % of the total brain volume. The white matter includes the major commissural tracts, the cortical association fibers, and all the cortical afferent and efferent fibers.
