This chapter discusses some of the methodological issues that arise when using noninvasive measures of neural activity (specifically, functional magnetic resonance imaging [fMRI] and event-related potentials [ERPs]). It focuses on how studies can be designed to identify age-related differences in brain activity associated with memory processes free from the influence of confounding variables that, by virtue of their correlation with age, might masquerade as differences inherent to the aging process. Whereas some of these variables are relevant to fMRI and ERP studies of aging in any cognitive domain, others are more specific to studies of episodic memory.

Keywords: fMRI; event-related potentials; neural activity; episodic memory; aging
