In this Review, we describe the singular success of attractor neural network models in
describing how the brain maintains persistent activity states for working memory, corrects …

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 …

Background Neuronal networks in the brain include glutamatergic principal neurons and
GABAergic interneurons (GABA, γ-aminobutyric acid). The latter may be a minority cell type …

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 …

The hippocampal dentate gyrus is often viewed as a segregator of upstream information.
Physiological support for such function has been hampered by a lack of well-defined …

Granule cells in the dentate gyrus of the hippocampus are thought to be essential to memory
function by decorrelating overlap** input patterns (pattern separation). A second …

Brain circuitry processes information by rapidly and selectively engaging functional neuronal
networks. The dynamic formation of networks is often evident in rhythmically synchronized …

To determine how hippocampal backprojections influence spatially periodic firing in grid
cells, we recorded neural activity in the medial entorhinal cortex (MEC) of rats after …

The medial entorhinal cortex (MEC) creates a neural representation of space through a set
of functionally dedicated cell types: grid cells, border cells, head direction cells, and speed …
