The paper challenges the idea that the nucleus reuniens acts as a relay between prefrontal cortex and hippocampus, showing instead that it contains distinct circuits with separate projections.

This study shows neuronal hyperactivity triggers C1q deposition on synapses, leading to synapse loss, and identifies immunoglobulins as involved in this process.

This study introduces a temporally structured olfactory task for mice to isolate relational structure from sensory cues and reward, showing that dopamine prediction errors and ventral hippocampal activity are linked to learned temporal structures.

The paper shows that combining environmental features and behavioural outcomes in models of the prefrontal cortex and hippocampus enables contextual inference and flexible behaviour.

This study shows acetylcholine reflects uncertainty during hidden state inference in mice performing a probabilistic task.

The paper shows that dopamine release in the nucleus accumbens during instrumental learning reflects Bayesian inference of probabilistic beliefs about hidden environmental states.

This study shows that ventral hippocampus CA1 is necessary for mice to perform hidden state inference in a 2-armed bandit task using abstract contextual representations.

The paper identifies two genetically distinct neuronal populations in the ventral hippocampus projecting to prefrontal cortex, showing differential gene expression linked to mental illness.

This study identifies two distinct hippocampus to prefrontal cortex pathways that differentially regulate approach and avoidance behaviors.

This study identifies parallel excitatory and inhibitory pathways from the basal amygdala to the ventral hippocampus in mice, showing how BA inhibition gates place-value associations through specific connectivity.

This study investigates how ghrelin signaling in the ventral hippocampus influences feeding behavior by modulating specific neuronal circuits in mice.

The paper investigates input-output relationships of ventral subiculum neurons in mice, revealing spatial and target-specific input biases.
