The paper reactivates hippocampal fear engrams across different contexts and identifies brain-wide network changes associated with distinct defensive behaviors.

This study shows that social interactions can reactivate fear memories in male mice, enhancing memory recall through hippocampal engram reactivation.

This study shows chronic optogenetic stimulation of hippocampal engrams in male mice enhances specific social behaviors but not others, with no detectable changes in neural activity markers.

This study shows that odor can delay the de-contextualization of fear memories, maintaining hippocampal dependence even at remote time points.
