Que PASA? The posterior-anterior shift in aging.
The present functional magnetic resonance imaging findings demonstrate the validity, function, and generalizability of PASA, as well as its importance for the cognitive neuroscience of aging.
Task-independent and task-specific age effects on brain activity during working memory, visual attention and episodic retrieval.

The results indicate that both common and specific factors play an important role in cognitive aging, and suggest that age-related hippocampal deficits may have a global effect in cognition.
Triple dissociation in the medial temporal lobes: recollection, familiarity, and novelty.
This is the first study to reveal a triple dissociation within the MTL associated with distinct retrieval processes, and this finding has direct implications for current memory models.
Brain Activity during Episodic Retrieval of Autobiographical and Laboratory Events: An fMRI Study using a Novel Photo Paradigm
Compared with the controlled laboratory condition, the controlled autobiographical condition elicited greater activity in regions associated with self-referential processing (medial prefrontal cortex), visual/ spatial memory (visual and parahippocampal regions), and recollection (hippocampus).
The spatiotemporal dynamics of autobiographical memory: neural correlates of recall, emotional intensity, and reliving.

The findings indicate dynamic recruitment of emotion-, memory-, and sensory-related brain regions during remembering and their dissociable contributions to phenomenological features of the memories.
Effects of healthy aging on hippocampal and rhinal memory functions: an event-related fMRI study.

These findings indicate that older adults compensate for hippocampal deficits by relying more on rhinal cortex, possibly through a top-down frontal modulation.
Neural Correlates of Relational Memory: Successful Encoding and Retrieval of Semantic and Perceptual Associations
Only one region in the entire brain was associated with RM in general (i.e., for both semantic and perceptual ESA and RSA): the left hippocampus, highlighting the fundamental role of the hippocampus in RM.
When less means more: deactivations during encoding that predict subsequent memory
Neuroanatomical correlates of episodic encoding and retrieval in young and elderly subjects.

It is concluded that the reduced performance in the ELD-RED group is likely to be due to MTL dysfunction during encoding, and the lack of differences observed in relation to retrieval success suggests that ageing does not affect the processes that support the actual recovery of information.
