This study investigates how semantic integration demands affect brain network interactions across the lifespan using fMRI and behavioral data.

This study examines age-related changes in functional brain network architecture during semantic word retrieval, finding increased coupling, reduced segregation, and more hubs in older adults despite intact semantic abilities.

This paper synthesizes five fMRI studies to examine the role of the angular gyrus in semantic cognition, finding consistent deactivation during non-semantic tasks and task-specific activation patterns.
