Integration of ethologically defined anxiety-related behaviors in the ventral hippocampus

The paper identifies specific anxiety-related behaviors in the ventral hippocampus and shows how distinct neuronal subclasses gate risk-assessment strategies during anxiety.

Hippocampus facilitates reinforcement learning under partial observability

This study uses deep reinforcement learning to show that hippocampal circuitry enables learning in partially observable environments, aligning with animal behavior and experimental data.

Scaling of ventral hippocampal activity during anxiety

This study investigates how ventral hippocampal activity scales with anxiety levels in mice using behavioral, electrophysiological, and computational methods.

Hippocampal contextualization of social rewards

This study shows that ventral hippocampus neurons distinguish contexts with social rewards and that LC projections support memory encoding of these contextual representations.

Firing patterns of ventral hippocampal neurons predict the exploration of anxiogenic locations

This study shows that ventral hippocampal neuron firing patterns predict exploration of anxiogenic locations in rats.
