The spontaneous replay of patterns of activity related to past experiences and memories is a
striking feature of brain activity, as is the coherent activation of sets of brain areas …

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 …

BACKGROUND Ever since Edward Tolman's proposal that comprehensive cognitive maps
underlie spatial navigation and, more generally, psychological functions, the question of …

Adult neurogenesis in the dentate gyrus of the hippocampus is highly regulated by a number
of environmental and cell-intrinsic factors to adapt to environmental changes. Accumulating …

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 …

Sharp wave ripples (SPW‐Rs) represent the most synchronous population pattern in the
mammalian brain. Their excitatory output affects a wide area of the cortex and several …

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

Applications that generate huge amounts of data in the form of fast streams are becoming
increasingly prevalent, being therefore necessary to learn in an online manner. These …

The precise functional role of the hippocampus remains a topic of much debate. The
dominant view is that the dorsal (or posterior) hippocampus is implicated in memory and …

The discovery of neuronal systems dedicated to computing spatial information, composed of
functionally distinct cell types such as place and grid cells, combined with an extensive body …
