White matter scaffold offers new view of the brain

Neural map may explain why some injuries are worse than others

BRAIN TRUST  These white matter tracts (indicated by red, blue and green lines) in the brain are particularly vulnerable to injury, a new study suggests.

Buried amid the complexity of the human brain, a newly described scaffold carries important messages from one place to another. A map of the scaffold, which reveals intricate connections made by bundles of nerve fibers called white matter tracts, could help explain why some brain injuries are particularly devastating.
