The paper examines how amyloid-beta accumulation varies across cognitive and non-cognitive brain networks in preclinical Alzheimer's disease and finds higher accumulation in cognitive networks with age and in amyloid-positive individuals.

This study characterizes human cerebral cortex metabolic connectivity using PET-FDG data, finding a superior-inferior gradient driven by low-frequency signals.

The paper examines the relationship between fMRI-based network metrics and glucose metabolism across different brain states and diseases, finding state- and network-dependent metabolic associations.

The paper examines age-related GABA level changes in cognitively-intact oldest-old adults, finding that GABA decline flattens after age 80, suggesting a link between GABAergic function and successful cognitive aging.

This study examines how network segregation in the brains of healthy oldest-old adults relates to cognitive performance and processing speed.
