“The absence of a college education seems to result in greater declines in brain health during older age, measured from an individual’s brain network organization,” he said. “We believe that decreasing brain network specialization is a general property of aging systems. “We believe that decreasing brain network specialization is a general property of aging systems. Wig’s team plans to use the existing data to evaluate whether analogous brain network changes exist in aging mice. If they find similar patterns of degradation in mice, researchers plan to study the factors they believe affect health.
