Complex patterns of neural activity appear during up-states in the neocortex and sharp
waves in the hippocampus, including sequences that resemble those during prior …

Long-term memories are believed to be stored in the synapses of cortical neuronal
networks. However, recent experiments report continuous creation and removal of cortical …

During spatial exploration, neural circuits in the hippocampus store memories of sequences
of sensory events encountered in the environment. When sensory information is absent …

During systems consolidation, memories are spontaneously replayed favoring information
transfer from hippocampus to neocortex. However, at present no empirically supported …

Brain networks store new memories using functional and structural synaptic plasticity.
Memory formation is generally attributed to Hebbian plasticity, while homeostatic plasticity is …

Abstract Background/Introduction In recurrent neural networks in the brain, memories are
represented by so-called Hebbian cell assemblies. Such assemblies are groups of neurons …

The architecture of cortex is flexible, permitting neuronal networks to store recent sensory
experiences as specific synaptic connectivity patterns. However, it is unclear how these …

This simulation study explores how structural processes and synaptic consolidation during
hippocampal memory replay can improve the performance of neocortical neural networks by …

Memory consolidation assimilates recent experiences into long-term memory. This process
requires the replay of learned sequences, although the content of these sequences remains …

Sequences of spiking activity have been heavily implicated as potential substrates of
memory formation and retrieval across many species. A parallel line of recent evidence also …
