Memory engrams: Recalling the past and imagining the future

SA Josselyn, S Tonegawa - Science, 2020 - science.org
BACKGROUND The idea that memory is stored as enduring changes in the brain dates

Forgetting as a form of adaptive engram cell plasticity

TJ Ryan, PW Frankland - Nature Reviews Neuroscience, 2022 - nature.com
One leading hypothesis suggests that memories are stored in ensembles of neurons (or
'engram cells') and that successful recall involves reactivation of these ensembles. A logical …

Engram neurons: Encoding, consolidation, retrieval, and forgetting of memory

A Guskjolen, MS Cembrowski - Molecular psychiatry, 2023 - nature.com
Tremendous strides have been made in our understanding of the neurobiological substrates
of memory–the so-called memory “engram”. Here, we integrate recent progress in the …

Neuromodulated spike-timing-dependent plasticity, and theory of three-factor learning rules

N Frémaux, W Gerstner - Frontiers in neural circuits, 2016 - frontiersin.org
Classical Hebbian learning puts the emphasis on joint pre-and postsynaptic activity, but

Spike timing-dependent plasticity and memory

D Debanne, Y Inglebert - Current Opinion in Neurobiology, 2023 - Elsevier

[HTML][HTML] Examining the engram encoding specificity hypothesis in mice

JH Jung, Y Wang, AJ Mocle, T Zhang, S Köhler… - Neuron, 2023 - cell.com
According to the encoding specificity hypothesis, memory is best recalled by retrieval cues
that overlap with training cues. Human studies generally support this hypothesis. However …
