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.

Locus coeruleus noradrenergic neurons phase-lock to prefrontal cortical and hippocampal infra-slow rhythms which synchronize with behavioral events

This study shows that locus coeruleus neurons phase-lock to infra-slow rhythms in prefrontal cortex and hippocampus during an attentional task, suggesting a role for noradrenaline in behavioral adaptation.
