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.
In neuroanatomy, the centrum semiovale, semioval center or centrum ovale [1] is the central area of white matter found underneath the cerebral cortex. [2] The white matter, located in each hemisphere between the cerebral cortex and nuclei, as a whole has a semioval shape.
The claustrum has the differential ability to select between task-relevant information and task-irrelevant information to provide directed attention. It contains the highest density of connecting white matter tracts in the cortex. This supports the notion of networking and coordination among different regions of the brain. [12]
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
Embryonic vertebrate subdivisions of the developing human brain hindbrain or rhombencephalon is a developmental categorization of portions of the central nervous system in vertebrates. It includes the medulla , pons , and cerebellum .
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 ...
lower white matter hyperintensity volume, indicating less damage to the white matter in the brain. increased fractional anisotropy, indicating well-organized and healthy white matter connections.
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.
