This study shows that the thalamic nucleus reuniens coordinates prefrontal-hippocampal theta oscillations to suppress extinguished fear in rats.

This study shows that ventral hippocampus inactivation removes context-dependence in two-way signaled avoidance behavior in male rats, while dorsal hippocampus inactivation has no effect.

This study investigates context-dependent flight behavior in rats, showing that contextual fear influences flight responses and that amygdala inactivation reduces both contextual and flight behaviors.

This study shows that the nucleus reuniens (RE) is essential for precise hippocampal-dependent contextual fear memory encoding but not retrieval in rats.
