Parallel emergence of stable and dynamic memory engrams in the hippocampus

T Hainmueller, M Bartos - Nature, 2018 - nature.com
During our daily life, we depend on memories of past experiences to plan future behaviour.
These memories are represented by the activity of specific neuronal groups or 'engrams' …

Reactivation predicts the consolidation of unbiased long-term cognitive maps

AD Grosmark, FT Sparks, MJ Davis, A Losonczy - Nature Neuroscience, 2021 - nature.com
Spatial memories that can last a lifetime are thought to be encoded during 'online'periods of
exploration and subsequently consolidated into stable cognitive maps through their …
