Although the parahippocampal cortex (PHc) is known to be critical for memory formation, little is known about what is encoded by this area. Using multi‐voxel pattern analysis of high‐resolution functional magnetic resonance imaging (MRI) data, we examined responses to blocks of categorically coherent stimuli and found that patterns of activity in PHc were selective for not only scenes, but also for other nonspatial object categories (e.g., faces and toys). This pattern of results was also found…

Distributed category‐specific recognition‐memory signals in human perirhinal cortex
TLDR
These findings provide support for proposals, recently raised in the neurophysiological literature, that the prior occurrence of objects is coded by distributed PrC representations and suggest that the stimulus category to which an item belongs shapes the organization of these distributed representations.
Category‐specificity in the human medial temporal lobe cortex
TLDR
Measuring differential BOLD responsiveness to objects, scenes, and other stimulus categories, an anatomical ROI based approach was undertaken in an effort to understand the response profile underlying a double dissociation between an anterior PRc response to objects and a posterior PHC response to scene stimuli.
Evidencing a place for the hippocampus within the core scene processing network
TLDR
The frequency and consistency of individual scene‐preferential responses within posterior parahippocampal gyrus, RSC, retrosplenial cortex, and transverse occipital sulcus is characterised by analysing a large dataset in which participants performed a one‐back working memory task for scenes, objects, and scrambled objects.
Medial temporal lobe regions mediate complex visual discriminations for both objects and scenes: A process-based view.
TLDR
Preliminary evidence for BOLD activation in the PRC during a complex visual discrimination task for objects and scenes, as well as robust activation for both stimulus types in PHC and HC, support a content-specific view of medial temporal lobe functioning.
Multivariate pattern analysis of the human medial temporal lobe revealed representationally categorical cortex and representationally agnostic hippocampus
TLDR
The results suggest that PHC, PRC, and RSC/PCC are representationally categorical and the hippocampus is more representationally agnostic, which is concordant with the hypothesis of the role of the hippocampus in pattern separation.
Category specificity in the medial temporal lobe: A systematic review
TLDR
Existing evidence for regional specialization in the MTL for three categories of visual stimuli: faces, objects, and scenes is evaluated and the need for the development of theoretical models of MTL function that can accommodate the differential patterns of specificity observed in theMTL is highlighted.
Dynamic changes in the medial temporal lobe during incidental learning of object-location associations.
TLDR
The results suggest that associative encoding relies on complex patterns of neural activity in MTL that cannot be expressed by simple increases or decreases of blood oxygenation level-dependent signal during learning.
Ultra-High-Field fMRI Reveals a Role for the Subiculum in Scene Perceptual Discrimination
TLDR
It is demonstrated that the discrimination of scenes, relative to faces and objects, recruits the anterior subicular region of the hippocampus, regardless of whether scenes were subsequently remembered or forgotten.
Multiple object properties drive scene-selective regions.
TLDR
It is hypothesized that scene-preferring regions might process both visual qualities unique to scenes and spatial qualities that can appertain to either scenes or objects.
Decoding Representations of Scenes in the Medial Temporal Lobes
TLDR
This study uses a combination of high‐resolution functional magnetic resonance imaging, multivariate pattern analysis, and a simple decision making task to test specific hypotheses concerning the role of the medial temporal lobe (MTL) in scene processing.

A cortical representation of the local visual environment
TLDR
Evidence is presented that a particular area within human parahippocampal cortex is involved in a critical component of navigation: perceiving the local visual environment, and it is proposed that the PPA represents places by encoding the geometry of the local environment.
Distinct roles for medial temporal lobe structures in memory for objects and their locations.
TLDR
Using functional magnetic resonance imaging to determine whether the perirhinal and parahippocampal cortices show differential memory-related activity for spatial and object recognition memory supports the idea that MTL structures make distinct contributions to recognition memory performance.

TLDR
The extent to which common stimuli that are nonspatial by nature, namely faces, activate the PHC, although their perception is typically associated with other cortical structures is investigated, indicating that thePHC should be regarded as mediating contextual associations in general and not necessarily spatial or episodic information.
