Results provide direct evidence that, even when stimulus type is held constant, the PRc and PHc are supp preferentially involved in Episodic memory, which reflects the ability to remember that an object was previously presented in a specific temporal or spaial context.

It was found that young healthy adults at increased genetic risk of AD (ApoE-e4 carriers) showed increased scene-related activity in posterior cingulate cortex (PCC); a region affected, structurally, early in AD.

Brain activation with functional magnetic resonance imaging in response to covert reinstatement of a cognitive context, prior to presenting an item memory probe is measured to suggest that PHc activation is correlated with cognitive context retrieval.

This study used fMRI to determine the extent to which the recruitment of regions in the recollection network is contingent on context reinstatement, and implicate medial temporal areas in the retrieval of semantic context, contributing to, but dissociation from, recollective experience.
Memory for items and relationships among items embedded in realistic scenes: disproportionate relational memory impairments in amnesia.

The results are consistent with the proposed role of the hippocampus in relational memory binding and representation, even at short delays, and suggest that the hippocampus may also contribute to successful item memory when items are embedded in complex scenes.
Object and spatial mnemonic interference differentially engage lateral and medial entorhinal cortex in humans
- Biology, PsychologyProceedings of the National Academy of Sciences
- 2014
A conceptual model of how object and spatial interference are reduced in the regions providing input to the hippocampus, allowing rich, distinct memories to be built is proposed, and novel evidence for a domain-selective dissociation between lateral and medial entorhinal cortex in humans and between perirhinal and parahippocampal cortex as a function of information content is demonstrated.

The present data suggest a gradient of content sensitivity from posterior (parahippocampal) to anterior (perirhinal) MTL cortex, with MTL cortical regions differentially contributing to successful encoding based on event content.

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.

These findings provide compelling support for the hypothesis that rapid item–context binding is a function of the hippocampus, rather than the parahippocampal cortex, with the former acting to detect relational novelty of this nature through its function as a match–mismatch detector.

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.
