White matter is named for its relatively light appearance resulting from the lipid content of myelin. However, the tissue of the freshly cut brain appears pinkish-white to the naked eye because myelin is composed largely of lipid tissue veined with capillaries.
30 oct. 2023 · In the brain, white matter is situated beneath the gray matter of the cortex and connects various gray matter areas within the brain to each other. It contains three major groups of axons: association fibers, commissural fibers, and projection fibers.
18 sept. 2023 · White matter is located in the deep parts of the brain while gray matter makes up the outer surface of the brain. White matter essentially acts as the brain’s communication network, connecting different parts of gray matter and facilitating coordinated brain function.
1 nov. 2016 · Abstract. Whereas the cerebral cortex has long been regarded by neuroscientists as the major locus of cognitive function, the white matter of the brain is increasingly recognized as equally critical for cognition.
21 mai 2023 · White matter in the brain contains nerve fibers (axons), which are surrounded by a protective fatty covering called the myelin sheath. The myelin is what gives white matter its white color. White matter axons connect nerve cells (neurons).
15 feb. 2022 · The taxonomic analogue of a gray matter brain region is a white matter tract or bundle: a collection of myelinated axons that share a meaningful combination of properties that may include connectivity, volume, gross morphology, trajectory, ontogeny, phylogeny, function, and susceptibility to disease or injury processes.
6 aug. 2019 · The brain's white matter is situated under the surface gray matter or cerebral cortex of the brain. White matter is composed of nerve cell axons, which extend from the neuron cell bodies of gray matter. These axon fibers form connections between nerve cells.
