The paper identifies aggrecan as an extracellular matrix protein that stabilizes fear memories by altering neuronal excitability in the hippocampal dentate gyrus.

This study identifies a thalamic circuit that biases hippocampal coding toward aversive stimuli and influences approach-avoidance behaviors.

The paper identifies vCA1 SST interneurons as key regulators of avoidance behavior by showing their selective recruitment during avoidance and their role in shaping behavioral responses in threatening environments.

This study investigates psilocybin's effects on mouse behavior through a multi-laboratory collaboration, finding robust acute effects but inconsistent persistent effects.

This study investigates how the ventral hippocampus encodes environmental stimuli, finding that vCA1 neurons represent stimulus identity, sensory features, and intensity but not valence.

The paper identifies and rescues dysfunctional neural dynamics in the vCA1-BLA circuit of stress-susceptible mice, improving anhedonia and resilience.

The paper tracks how neurons in the dorsal and ventral hippocampus update odor-outcome associations over learning phases using 2-photon calcium imaging.

The paper shows that position, direction, and speed in the hippocampus are encoded by overlapping neuronal ensembles in dentate gyrus and CA1, suggesting a distributed neural code rather than single-cell specialization.

The paper identifies a neuronal ensemble in the nucleus accumbens that expands with pair bonding in prairie voles, suggesting it underlies bond formation and maturation.
