Witryna5 lip 2024 · The degree of myelination affects the appearance of the brain parenchyma on CT. In adults, the cerebral cortex has intermediate attenuation that is slightly higher relative to normal white matter. For infants younger than 6 months, differentiation of white matter relative to gray matter is limited secondary to the immature myelination of … Witryna17 wrz 2024 · When OPCs get a signal from “helpful” microglia, the OPCs first increase in number. These new cells become immature oligodendrocytes, which have branches but do not yet myelinate axons. Eventually, immature oligodendrocytes become adult, myelinating oligodendrocytes that can wrap myelin around many different axons. dakota county child mental healthWitryna1 wrz 1997 · We hypothesized that hydrocephalus in young animals could cause a delay in myelination.
