  Grey matter - Wikipedia, the free encyclopedia
Grey matter is the major part of the nervous system in which the nerve impulses for all kinds of mental functions are produced and then sent away to be carried to their target organs by white matter.
The cerebral cortex and the basal ganglia, such as the putamen and the caudate nucleus, are composed of grey matter.
In addition, grey matter - unlike white matter - does not have a myelin sheath and does not regenerate after injury.

 White matter - Wikipedia, the free encyclopedia
It is composed of myelinated nerve cell processes, or axons, which connect various grey matter areas (the locations of nerve cell bodies) of the brain to each other and carry nerve impulses between neurons.
Aggregates of grey matter such as the basal ganglia (caudate nucleus, putamen, globus pallidus, subthalamic nucleus, nucleus accumbens) and brain stem nuclei (red nucleus, substantia nigra, cranial nerve nuclei) are spread within the cerebral white matter.
The cerebellum is structured in a similar manner as the cerebrum, with a superficial mantle of cerebellar cortex, deep cerebellar white matter (called the "Arbor Vitae") and aggregates of grey matter surrounded by deep cerebellar white matter (dentate nucleus, globose nucleus, emboliform nucleus, and fastigial nucleus).

 BBC News | SCI/TECH | IQ linked with amount of grey matter
Grey matter, so named because it looks grey to the naked eye, refers to the areas of the brain that are mainly composed of the heads of nerve cells.
White matter is the name given to parts of the brain and spinal cord that are responsible for communication between the various grey matter regions and between the grey matter and the rest of the body.
Scientists have long suspected that grey matter is the seat of intelligence in the brain, but this is the first time the tissue has been studied with a medical brain scanner and linked with IQ tests.

 grey matter - multiple sclerosis encyclopaedia   (Site not responding. Last check: 2007-11-03)
The grey matter is the areas where the actual "processing" is done whereas the white matter provides the communication between different grey matter areas and between the grey matter and the rest of the body.
The grey matter is so-called because in section it has a grey colour due to all the grey nuclei in the cells that make it up.
The neurons in the grey matter consist of neuronal cell bodies and their dendrites, the short protrusions that communicate with immediately neighbouring neurons in the CNS.

 Nature Reviews Neuroscience - Highlights
They found that there was a greater loss of grey matter in patients with schizophrenia than in normal adolescents, and that the loss followed a specific spatial pattern as time progressed.
Previous work has shown that grey matter deficits in some areas of the brain in adult schizophrenic patients and their families are attributable to genetic factors, whereas in other areas they seem to be related to environmental factors.
Grey matter deficits in different brain areas also show interesting correlations with the clinical progression of the disease.

 BioEd Online: Grey matter matters for intellect
A brain imaging study suggests that human intellect is based on the volume of grey matter in certain brain regions, challenging alternative views about the basis of intelligence.
Richard Haier from the University of California, Irvine, and colleagues used magnetic resonance imaging to measure the amount of grey matter in the brains of 47 adults, who also took standard IQ tests.
Grey matter is a diffuse network of brain regions thought to be involved in information processing.

While the health consequences of smoking are well known, it is the first time that brain mapping has been used to document the volume and density of the grey matter in smokers’ brains.
Grey matter, so named because it looks grey to the naked eye, consists largely of the cell bodies of neurons, the heads of nerve cells.
He said: "It could be that smokers have a smaller brain, or it could mean that smoking damages the grey matter in the brain.

Mechelli and his team used structural brain imaging to compare the size of the grey matter in the brains of 25 monolinguals, 25 early bilinguals who learned a second language before the age of five and 33 late bilinguals.
In the bilinguals, the grey matter in the left inferior parietal cortex was larger than in the monolinguals or the bilinguals who picked up the second language between the ages of 10-15.

 Example: Grey and White Matter of the Spinal Cord   (Site not responding. Last check: 2007-11-03)
The terms "grey" and "white" matter are always a source of confusion to students of histology: they're not very descriptive of what you see in a microscope.
Even in regions like the grey matter of the spinal cord, neurons are a small minority of the numbers of cells present, even though they're functionally the most important ones.
So, in the context of histology is that when you look at "grey matter" under the microscope, most of what you see is the fiber tracts, and you need to be alert to the presence of neuron somata scattered in it to recognize it.

Now, however, a common view is that more subtle characteristics are likely to be involved, such as the speed at which nerve impulses travel in the brain, or the number of neuronal connections present.

 ::NISAD::News and Events::NISAD Scientists Awarded Major Research Grant::   (Site not responding. Last check: 2007-11-03)
Studies have confirmed that the onset of schizophrenia is associated with a depletion of density in areas of the brain's grey matter (the cortex), where high-level processing is done, but how this depletion relates to the impaired thinking, paranoia, delusions and other symptoms of the illness has remained unknown.
The main difficulty of answering this question is that the billions of grey matter cells called the cortex are concentrated in a layer just under the surface of the brain, and the wrinkled surface of each brain is as subtly unique as the contours of each human face.
The chief objective of the study was to show for the first time that areas of depleted grey matter density in schizophrenia-affected brains were directly involved in producing core deficits such as impaired thinking.
