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.

Threat-dependent scaling of prelimbic dynamics to enhance fear representation

The paper shows that the prelimbic cortex dynamically adjusts its neuronal activity to represent different states of freezing behavior in response to threats, which is necessary for fear memory.
