Summary

The cognitive neuroscience of aging is a large and diverse field seeking to understand cross-sectional differences and longitudinal changes in brain structure and function. Research in this field also investigates how brain differences or changes influence behavior in later life. There is consistent evidence indicating that cross-sectionally the brain is smaller in older adults (OA) relative to younger adults (YA), and this is due to longitudinal change over time. Furthermore, there are differences in functional activation patterns and the functional network architecture in the aging brain, both of which may contribute to the behavioral differences experienced by OA. Most notably, the differences in functional activation patterns suggest that perhaps the aging brain may compensate for the impacts of aging in an attempt to preserve performance. As such, several frameworks for understanding the processes of aging have taken hold resulting in testable hypotheses that link brain function and structure to behavior. Finally, in Alzheimer’s Disease, cognitive neuroscience methodologies have provided additional insights into the impacts of the disease on brain structure, function, and behavior.
