Deconstruction of a memory engram reveals distinct ensembles recruited at learning

This study identifies distinct neuronal ensembles in dorsal CA1 that are differentially active during associative fear memory acquisition and reveals which ensembles form the core engram.

Extinction and subsequent updating of innate fear responses to a visual looming stimulus rely on hippocampus-dependent mechanisms

The paper shows that innate fear responses to visual looming stimuli in mice can be reduced through repeated exposure and that hippocampal engrams are required for learned fear responses.

Natural forgetting reversibly modulates engram expression

This study investigates how forgetting modulates engram expression using a mouse model, showing that memory can be preserved, retrieved, or forgotten through optogenetic and pharmacological interventions.

Adaptive Expression of Engrams by Retroactive Interference

This study shows that retroactive interference reduces engram cell reactivation but can be reversed by optogenetic stimulation or environmental cues, indicating adaptive forgetting mechanisms.
