DOI: 10.1002/hipo.22824
Abstract: 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 brief events, often termed “replay” in the scientific literature, are largely… read more here.

DOI: 10.1002/hipo.23497
Abstract: The hippocampus is a critical component of a mammalian spatial navigation system, with the firing sequences of hippocampal place cells during sleep or immobility constituting a “replay” of an animal's past trajectories. A novel spatial… read more here.

DOI: 10.1007/s10772-019-09602-z
Abstract: The easy implementation of replay attacks by a fraudster poses a severe threat to automatic speaker verification (ASV) technology than the other spoofing attacks like speech synthesis and voice conversion. Replay attacks refer to an… read more here.

DOI: 10.1016/j.neuron.2021.12.005
Abstract: The neural circuit mechanisms underlying observational learning, learning through observing the behavior of others, are poorly understood. Hippocampal place cells are important for spatial learning, and awake replay of place cell patterns is involved in… read more here.

DOI: 10.1038/s41467-018-06213-1
Abstract: The hippocampus replays experiences during quiet rest periods, and this replay benefits subsequent memory. A critical open question is how memories are prioritized for this replay. We used functional magnetic resonance imaging (fMRI) pattern analysis… read more here.

DOI: 10.1073/pnas.2205211120
Abstract: Theories of neural replay propose that it supports a range of functions, most prominently planning and memory consolidation. Here, we test the hypothesis that distinct signatures of replay in the same task are related to… read more here.

DOI: 10.1089/g4h.2022.0118
Abstract: Stroke is a leading cause of chronic motor disability. While physical rehabilitation can promote functional recovery, several barriers prevent patients from receiving optimal rehabilitative care. Easy access to at-home rehabilitative tools could increase patients' ability… read more here.

DOI: 10.1101/2022.07.26.501588
Abstract: Replay of neuronal sequences in the hippocampus during resting states and sleep play an important role in learning and memory consolidation. Consistent with these functions, replay sequences have been shown to obey current spatial constraints.… read more here.
