Abstract There is considerable evidence that the hippocampal system contributes both to (1) the temporary maintenance of memories and to (2) the processing of a particular type of memory representation. The findings on amnesia suggest that these two distinguishing features of hippocampal memory processing are orthogonal. Together with anatomical and physiological data, the neuropsychological findings support a model of cortico-hippocampal interactions in which the temporal and representational… 
Hippocampus, delay neurons, and sensory heterogeneity
TLDR
A model of cortico-hippocampal interactions in which the temporal and representational properties of hippocampal memory processing are mediated separately is proposed, which proposes that neocortical association areas maintain shortterm memories for specific items and events prior to hippocampal processing as well as providing the final repositories of long-term memory.
The Episodic Memory System: Neurocircuitry and Disorders
TLDR
A growing body of evidence is converging on a functional organization of the cortical, subcortical, and MTL structures that support the fundamental features of episodic memory in humans and animals.
Functional organization of the hippocampal memory system.
TLDR
The findings support the view that the cortex maintains various forms of memory representation and that hippocampal structures extend the persistence and mediate the organization of these codings.

Considerations arising from a complementary learning systems perspective on hippocampus and neocortex
TLDR
A framework for the organization of learning systems in the mammalian brain is discussed, in which the hippocampus and related areas form a memory system complementary to learning mechanisms in neocortex and other areas, and there is a trade‐off between the need for information‐preserving, structure‐extracting encoding of cortical traces and theneed for effective storage and recall of arbitrary traces.
Plasticity at hippocampal to prefrontal cortex synapses: Dual roles in working memory and consolidation
TLDR
The available evidence suggests that functional interactions between the hippocampus and prefrontal cortex in cognition and memory are more complex than previously anticipated, with the possibility for bidirectional regulation of synaptic strength as a function of the specific demands of tasks.

TLDR
Analysis of the role of the cerebellum in basic delay conditioning (stimuli overlap) indicates that the memories are formed and stored in the Cerebellar long-term depression is considered as a putative mechanism of memory storage.
The role of the hippocampus in mnemonic integration and retrieval: complementary evidence from lesion and inactivation studies
TLDR
These results, using a novel combination of behavioural assays, provide clear support for the view that patterns of stimulation can be encoded either elementally or configurally, and that disruption of hippocampal function leaves rats reliant on elemental processes.

The hippocampal system: Dissociating its functional components and recombining them in the service of declarative memory
TLDR
Recent relevant findings strengthen the argument that neocortical areas and the parahippocampal region maintain persistent encodings of specific single items and that the hippocampus mediates representations of the relations among these items.

Configural association theory: The role of the hippocampal formation in learning, memory, and amnesia
TLDR
How the theory can be applied to explain a wide range of impairments that have been observed when learning and memory tasks have been employed to assess the effect of hippocampal formation damage is illustrated.
Memory, amnesia, and the hippocampal system
TLDR
A cognitive neuroscience theory of memory is offered that accounts for the nature of memory impairment exhibited in human amnesia and animal models of amnesia, that specifies the functional role played by the hippocampal system in memory, and that provides further understanding of the componential structure of memory.

Theoretical arguments and empirical data are presented in favor of the hypothesis that the hippocampal system supports a declarative memory capacity in animals as well as humans. This view is
The hippocampal memory indexing theory.
TLDR
It is asserted that the reactivation of the stored hippocampal memory index will serve to also reactivate the associated unique array of neocortical areas and thus will result in a memorial experience.
Hippocampus, space, and memory
TLDR
It is proposed that the hippocampus is selectively involved in behaviors that require working memory, irrespective of the type of material (spatial or nonspatial) that is to be processed by that memory.
The medial temporal lobe memory system
TLDR
The medial temporal lobe memory system is needed to bind together the distributed storage sites in neocortex that represent a whole memory, but the role of this system is only temporary, as time passes after learning, memory stored in neoc cortex gradually becomes independent of medialporal lobe structures.

TLDR
Analysis of both new and existing data are presented to show that by classifying tasks in terms of the need to use a temporary memory store to retain temporally discontiguous information one can cut right across existing classifications as well as achieve a better fit to the data.
The primate hippocampal formation: evidence for a time-limited role in memory storage.
TLDR
Results show that the hippocampal formation is required for memory storage for only a limited period of time after learning, and as time passes, its role in memory diminishes, and a more permanent memory gradually develops independently of the hippocampus.
