TLDR
This work considers how space and time are integrated in the representation of memories in the hippocampal region, suggesting that the findings on spatial and temporal organization reflect a generalized mechanism for organizing memories.About:

Integrating time from experience in the lateral entorhinal cortex
Albert Tsao,Jørgen Sugar,Li Lu,Li Lu,Cheng Wang,James J. Knierim,May-Britt Moser,Edvard I. Moser +7 more
TL;DR: It is shown in freely foraging rats that temporal information is robustly encoded across time scales from seconds to hours within the overall population state of the lateral entorhinal cortex, suggesting that populations of lateral entorsal cortex neurons represent time inherently through the encoding of experience.

Space and Time: The Hippocampus as a Sequence Generator
TL;DR: It is suggested that hippocampal operations can be described by the sequential activity of neuronal assemblies and their internally defined rate of change without resorting to the concept of space or time.

The Geometry of Abstraction in the Hippocampus and Prefrontal Cortex

TL;DR: Neural representations in monkeys performing a task described by different hidden and explicit variables are characterized to elucidate how the brain and artificial systems represent variables in an abstract format while preserving the advantages conferred by high shattering dimensionality.

Coupled ripple oscillations between the medial temporal lobe and neocortex retrieve human memory
TL;DR: Intracranial EEG recordings successfully reveal the link between ripple oscillations and memory retrieval in the awake human brain and provide direct evidence that coupled ripples between the MTL and association cortex may underlie successful memory retrieved in the human brain.

TL;DR: The amnesic syndrome is presented as an extension of the theory to humans and the role of operators in the locale system is examined.

Distributed Hierarchical Processing in the Primate Cerebral Cortex
TL;DR: A summary of the layout of cortical areas associated with vision and with other modalities, a computerized database for storing and representing large amounts of information on connectivity patterns, and the application of these data to the analysis of hierarchical organization of the cerebral cortex are reported on.

Separate visual pathways for perception and action.
TL;DR: It is proposed that the ventral stream of projections from the striate cortex to the inferotemporal cortex plays the major role in the perceptual identification of objects, while the dorsal stream projecting from the stripping to the posterior parietal region mediates the required sensorimotor transformations for visually guided actions directed at such objects.
Journal ArticleDOI
A cortical representation of the local visual environment
TL;DR: 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.
Journal ArticleDOI
The Medial Temporal Lobe and Recognition Memory
TL;DR: 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.
