Engram mechanisms of memory linking and identity

A Choucry, M Nomoto, K Inokuchi - Nature Reviews Neuroscience, 2024 - nature.com
Memories are thought to be stored in neuronal ensembles referred to as engrams. Studies
have suggested that when two memories occur in quick succession, a proportion of their …

[HTML][HTML] Structured memory representations develop at multiple time scales in hippocampal-cortical networks

A Tambini, J Miller, L Ehlert, A Kiyonaga, M D'Esposito - bioRxiv, 2023 - ncbi.nlm.nih.gov
Influential views of systems memory consolidation posit that the hippocampus rapidly forms
representations of specific events, while neocortical networks extract regularities across …

Memory out of context: Spacing effects and decontextualization in a computational model of the medial temporal lobe

J Antony, XL Liu, Y Zheng, C Ranganath, RC O'Reilly - bioRxiv, 2022 - biorxiv.org
Some neural representations change slowly across multiple timescales. Here we argue that
modeling this “drift” could help explain the spacing effect (the long-term benefit of distributed …

Time after Time: Preserving Temporal Memories When Experiences Repeat

F Zou, BA Kuhl - Journal of Cognitive Neuroscience, 2024 - direct.mit.edu
Remembering when events occur in time is fundamental to episodic memory. Yet, many
experiences repeat over time creating the potential for interference when attempting to recall …

[HTML][HTML] Benefits of spaced learning are predicted by re-encoding of past experience in ventromedial prefrontal cortex

F Zou, BA Kuhl, S DuBrow, JB Hutchinson - bioRxiv, 2024 - ncbi.nlm.nih.gov
More than a century of research shows that spaced learning improves long-term memory.
Yet, there remains debate concerning why. A major limitation to resolving theoretical …
