In the quiet architecture of the aging mind, USC researchers have found that the brain's local wiring—thin nerve fibers called superficial white matter—may serve as a kind of structural grace, softening the cognitive consequences of gray matter loss in older adults. Studying 459 individuals in India, a population rarely invited into neuroimaging science, the team discovered that healthier white matter connections were most strongly tied to language ability and could buffer the mind against decline even as tissue shrinks. The finding reframes resilience not as the absence of loss, but as the pr
