Grey Matter News and Research

RSS

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

European project to look at the wiring of the brain during growth

One of the great questions of neurobiology, how the brain is built up during embryonic development, could be resolved by a young French scientist in an award winning project organised by the European Science Foundation (ESF) and the European Heads of Research Councils (EuroHORCS).

Fetal neurons play role in adult brain

Subplate neurons - once thought to die after directing the wiring of the cerebral cortex or gray matter - remain in the white matter of the adult brain in small numbers and maintain activity, communicating with other neurons in the brain said researchers from Baylor College of Medicine and the University of Alabama at Birmingham in a report that appears in today's issue of the Journal of Neuroscience

Hallucinations in schizophrenia linked to brain area that regulates emotion and processes human voices

For the first time, researchers using magnetic resonance imaging (MRI) have found both structural and functional abnormalities in specific brain regions of schizophrenic patients who experience chronic auditory hallucinations, according to a study published in the August issue of Radiology.

Brain lesions may be sign of more widespread disease in the brain

Lesions commonly seen on MRI in the brains of older patients may be a sign of potentially more extensive injury to the brain tissue, according to a recent study conducted by researchers at the Duke University Medical Center, in Durham, NC.

Simple test predicts a person's risk for developing dementia within six years with 87 percent accuracy

The test, developed in the study by the researchers, is a 14-point index combining medical history, cognitive testing, and physical examination. It requires no special equipment and can be given in a clinical setting such as a doctor's office or at a patient's bedside.

Research reveals that a greater volume of grey encephalic matter exists in the brain areas of the right parahippocampus

A study undertaken by researchers of the Universitat Jaume I of Castellon (UJI), the Universitat Autonoma of Barcelona (UAB) and the company Eresa reveals the existence of a different anatomy in small areas of the brain which could help explain why one same stimulus triggers anxiety in some people and not in others.

Brain cells 'talk' with each other in more ways than previously thought

Johns Hopkins scientists have discovered to their surprise that nerves in the mammalian brain's white matter do more than just ferry information between different brain regions, but in fact process information the way gray matter cells do.
