Backbone spiking sequence as a basis for preplay, replay, and default states in human cortex
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 …

Replay of cortical spiking sequences during human memory retrieval
Episodic memory retrieval is thought to rely on the replay of past experiences, yet it remains
unknown how human single-unit activity is temporally organized during episodic memory …

Replay bursts in humans coincide with activation of the default mode and parietal alpha networks
Our brains at rest spontaneously replay recently acquired information, but how this process
is orchestrated to avoid interference with ongoing cognition is an open question. Here we …

The content of hippocampal “replay”
BE Pfeiffer - Hippocampus, 2020 - Wiley Online Library
One of the most striking features of the hippocampal network is its ability to self‐generate
neuronal sequences representing temporally compressed, spatially coherent paths. These …

Pattern separation of spiketrains in hippocampal neurons
Pattern separation is a process that minimizes overlap between patterns of neuronal activity
representing similar experiences. Theoretical work suggests that the dentate gyrus (DG) …
