- 27 February 2002
The HAROLD model is a cognitive neuroscience model that integrates ideas and findings from psychology and neuroscience of aging that is supported by functional neuroimaging and other evidence in the domains of episodic memory, semantic memory, working memory, perception, and inhibitory control.
Imaging Cognition II: An Empirical Review of 275 PET and fMRI Studies
Analysis of regional activations across cognitive domains suggested that several brain regions, including the cerebellum, are engaged by a variety of cognitive challenges.

The results suggest that low- performing older adults recruited a similar network as young adults but used it inefficiently, whereas high-performing older adults counteracted age-related neural decline through a plastic reorganization of neurocognitive networks.
The parietal cortex and episodic memory: an attentional account

The answer to the episodic-memory puzzle requires us to distinguish between the contributions of dorsal and ventral parietal regions and between the influence of top-down and bottom-up attention on memory.
Cognitive neuroscience of emotional memory
Cognitive neuroscientists have begun to elucidate the psychological and neural mechanisms underlying emotional retention advantages in the human brain, revealing new insights into the reactivation of latent emotional associations and the recollection of personal episodes from the remote past.
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.
Age-Related Differences in Neural Activity during Memory Encoding and Retrieval: A Positron Emission Tomography Study
The results indicate that advanced age is associated with neural changes in the brain systems underlying encoding, recognition, and recall that take two forms: age- related decreases in local regional activity, which may signal less efficient processing by the old, and age-related increases in activity,Which may signal functional compensation.
Present and Future
Traditionally, cognitive aging research has been based on behavioral measures of cognitive performance such as response time and accuracy. Data have indicated that agerelated decline occurs in…
Task-independent and task-specific age effects on brain activity during working memory, visual attention and episodic retrieval.
- R. Cabeza, S. Daselaar, F. Dolcos, S. Prince, Matthew Budde, L. Nyberg
- PsychologyCerebral Cortex
- 1 April 2004
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.
- S. Daselaar, M. Fleck, R. Cabeza

- 1 October 2006
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.
