In the present fMRI study, we examined age-related differences in episodic richness on the spatiotemporal dynamics
of AM retrieval. Age-related reductions were primarily observed during the later elaboration processes of AM retrieval,
In sum, the present findings suggest that the age-related deficit in the episodic richness of AMs is associated
with an overall reduction in the rich elaboration of these memories, where older adults show less top-down
modulation of the PFC on the hippocampus.
