The role of recollection and familiarity in the functional differentiation of the medial temporal lobes
- Biology, PsychologyHippocampus
- 2010
There has been disagreement about whether recall/recollection is primarily mediated by the hippocampus and familiarity by the evolutionarily newer MTL cortices or whether the MTL mediates these kinds of memory in an integrated, homogeneous fashion.

A subsequent memory paradigm that assessed successful item encoding in addition to the encoding of two distinct episodic details, providing strong evidence for a role of the hippocampus in domain-general associative encoding and raising the possibility that PrC encoding operations in conjunction with hippocampal mechanisms contribute to later recollection of presented item details.
Medial Temporal Lobe Activity during Source Retrieval Reflects Information Type, not Memory Strength
- Psychology, BiologyJournal of Cognitive Neuroscience
- 2010
Results showed that encoding color information as an item detail improved source recognition in amnesic patients with recollection deficits, and qualitatively different patterns of results observed in PRc and hippocampus/PHc are consistent with the idea that different MTL regions process different types of episodic information.

Neural correlates of recognition memory for complex visual stimuli in the medial temporal lobe
- Psychology, Biology
- 2010
Three experiments were designed to compare competing models of MTL function by measuring, using functional magnetic resonance imaging, the neural correlates of successful recollection- and familiarity-based memory judgements for different types of complex visual stimuli, consistent with views that the perirhinal cortex and hippocampus are differentially involved in processing objects and scenes, rather than in supporting distinct kinds of memory process.
Recollection, familiarity, and content-sensitivity in lateral parietal cortex: a high-resolution fMRI study

The findings show that episodic retrieval relies on both content-sensitive and core recollective processes, and these can be differentiated from familiarity-based recognition memory.

The medial temporal lobe and recognition memory.
- Psychology, BiologyAnnual review of neuroscience
- 2007
Evidence from neuropsychological, neuroimaging, and neurophysiological studies of humans, monkeys, and rats indicates that different subregions of the MTL make distinct contributions to recollection and familiarity; the data suggest that the hippocampus is critical for recollection but not familiarity.
Triple dissociation in the medial temporal lobes: recollection, familiarity, and novelty.
- Psychology, BiologyJournal of neurophysiology
- 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.
Multiple routes to memory: Distinct medial temporal lobe processes build item and source memories
- Biology, PsychologyProceedings of the National Academy of Sciences of the United States of America

This work used event-related functional MRI to examine the relation between activation in distinct medial temporal lobe subregions during memory formation and the ability to later recognize an item as previously encountered and later recollect specific contextual details about the prior encounter.
Separating the Brain Regions Involved in Recollection and Familiarity in Recognition Memory
- Psychology, BiologyThe Journal of Neuroscience
- 2005
The neural substrates of recognition memory retrieval were examined in a functional magnetic resonance imaging study to separate activity related to recollection from that related to continuous variations in familiarity, indicating that recollection cannot be attributed to familiarity strength.

Results revealed that multiple left prefrontal cortical regions were engaged during attempts to recollect previous contextual details, regardless of the nature of the to-be-recollected details and of source recollection outcome (successful vs unsuccessful).

A functional magnetic resonance imaging study to compare the medial temporal lobe responses to changes in object identity and spatial configurations of objects found evidence for the predicted distinction between hippocampal and perirhinal cortical activations, although part of the hippocampus was also activated by identification of novel objects.

Content-specific associations between encoding- and recollection-related neural activity strongly support the reinstatement hypothesis of episodic retrieval.
