Brain, Meninges & CSF Anatomy
White matter
White matter is brain tissue made up mainly of nerve fibers that connect different regions.
In short: White matter
- The corpus callosum is a large white matter structure.
- It carries signals between brain regions.
- It contrasts with gray matter (nerve cell bodies).
- Its structures can be affected in encephalocele.
What it is
It is the brain's connecting fiber tissue, made of nerve fibers that link different regions. The corpus callosum, which connects the brain's two halves, is a major white matter structure.
Understanding White matter
White matter structures like the corpus callosum can be affected in encephalocele — for example, agenesis (absence) of the corpus callosum, which is sometimes seen as an associated finding. Because white matter carries signals between regions, its development is part of the overall picture imaging examines.
Why it matters
Understanding white matter helps families interpret findings like agenesis of the corpus callosum and see why the brain's connecting structures are part of the evaluation.
Common questions
What does white matter do?
Connects brain regions. Name a white matter structure. The corpus callosum.
Can it be affected in encephalocele?
Yes — for example, absence of the corpus callosum.
Bottom line
White matter connects brain regions, including via the corpus callosum, and can be affected in encephalocele.
