Growth of white matter in the adolescent brain: Myelin or axon?

摘要: White matter occupies almost half of the human brain. It contains axons connecting spatially segregated modules and, as such, it is essential for smooth flow information in functional networks. Structural maturation white continues during adolescence, reflected age-related changes its volume, well microstructure. Here I review recent observations obtained with magnetic resonance imaging typically developing adolescents and point out some known variations structural properties vis-a-vis brain function health disease. conclude by re-focusing interpretations MR-based studies from myelin to axon.
