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.
Location. White matter forms the bulk of the deep parts of the brain and the superficial parts of the spinal cord. Aggregates of grey matter such as the basal ganglia (caudate nucleus, putamen, globus pallidus, substantia nigra, subthalamic nucleus, nucleus accumbens) and brainstem nuclei (red nucleus, cranial nerve nuclei) are spread within ...
17 ian. 2023 · White matter modulates the distribution of action potentials, acting as a relay and coordinating communication between different brain regions. There are three main kinds of white matter tracts: projection, commissural, and association.
The cerebral WM contains fiber pathways that convey axons linking cerebral cortical areas with each other and with subcortical structures, facilitating the distributed neural circuits that subserve sensorimotor function, intellect, and emotion.
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.
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 iul. 2021 · White matter makes up about fifty percent of the human brain. Maturation of white matter accompanies biological development and undergoes the most dramatic changes during childhood and adolescence.
