White matter is the tissue through which messages pass between different areas of grey matter within the central nervous system. The white matter is white because of the fatty substance (myelin) that surrounds the nerve fibers (axons). This myelin is found in almost all long nerve fibers, and acts as an electrical insulation.
The arbor vitae / ˌ ɑːr b ɔːr ˈ v aɪ t iː / (Latin for "tree of life") is the cerebellar white matter, so called for its branched, tree-like appearance.In some ways it more resembles a fern and is present in both cerebellar hemispheres. [1]
The external capsule is a series of white matter fiber tracts in the brain. These fibers run between the most lateral (toward the side of the head) segment of the lentiform nucleus (more specifically the putamen) and the claustrum. The white matter of the external capsule contains fibers known as corticocortical association fibers.
However, detailed analyses of white matter microstructure revealed that superagers had higher fractional anisotropy and lower mean diffusivity — two measures related to brain decline at a ...
A new study examines how age-related brain changes could be linked to stroke recovery. Researchers suggest areas of age-related damage to parts of the brain containing white matter may influence ...
The human brain is the central organ of the nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
They wanted to find out if closely following the Mediterranean diet could improve brain health in Hispanic/Latino adults in the United States, specifically looking at white matter. White matter is ...
The projection fibers that make up the corona radiata also radiate out of the brain stem via the internal capsule. Cerebral white matter is viewed as an intricately organized system of fasciculi that facilitate the highest expression of cerebral activity. Part of corona radiata pathway in the brain
