The dentate gyrus (DG) has a key role in hippocampal memory formation. Intriguingly, DG
lesions impair many, but not all, hippocampus-dependent mnemonic functions, indicating …

Since the first place cell was recorded and the cognitive-map theory was subsequently
formulated, investigation of spatial representation in the hippocampal formation has evolved …

Animals associate cues with outcomes and update these associations as new information is
presented. This requires the hippocampus, yet how hippocampal neurons track changes in …

The hippocampus is famous for map** locations in spatially organized environments, and
several recent studies have shown that hippocampal networks also map moments in …

An organism's survival can depend on its ability to recall and navigate to spatial locations
associated with rewards, such as food or a home. Accumulating research has revealed that …

We update complementary learning systems (CLS) theory, which holds that intelligent
agents must possess two learning systems, instantiated in mammalians in neocortex and …

Neurons often respond to diverse combinations of task-relevant variables. This form of
mixed selectivity plays an important computational role which is related to the dimensionality …

We describe an integrative model that encodes associations between related concepts in
the human hippocampal formation, constituting the skeleton of episodic memories. The …

There is considerable research on the neurobiological mechanisms within the hippocampal
system that support spatial navigation. In this article I review the literature on navigational …

The hippocampal system is critical for storage and retrieval of declarative memories,
including memories for locations and events that take place at those locations. Spatial …
