Age links to brain fiber size differ among crossing fibers
Brain scans from 295 older adults linked age most strongly to smaller bundle size in the non-dominant groups of crossing nerve fibers.Brain scans from 295 older adults linked age most strongly to smaller bundle size in the non-dominant groups of crossing nerve fibers.

What changedBrain fiber-bundle size was lower at older ages, with steeper age associations in non-dominant than primary fibers
The catchCrossing-fiber complexity was confounded with tract identity and location
