VUMC scientists record powerful signal in the brain’s white matter

Vanderbilt researchers report that when people who are having their brains scanned by fMRI perform a task, like wiggling their fingers, certain signals increase in white matter throughout the brain, which has long been thought to play a lesser role the more the brain’s more energetic gray matter.

Tracking the aging brain

The macrostructure — volume, area and length — of the brain’s white matter is useful for studying aging and could be a sensitive marker for neurodegenerative disorders such as Alzheimer’s disease, Vanderbilt researchers reported.
