The paper shows that dopamine responses decrease rapidly before a hedonic switch during sodium satiation, tracking cumulative sodium intake in rats.

This study compares the representational geometry of human spatial memory and mouse CA1 during environmental deformations, finding similar geometries with differences in change resistance.

This study shows that dopamine activity in the mesolimbic system encodes the changing valence of sucrose in conditioned taste aversion, aligning with behavioral responses.

The paper shows that mouse CA1 neural representations in complex environments reflect predictive navigational histories, with similar compartments represented more similarly across individuals.

The paper identifies representational structure in CA1 remapping across brains and benchmarks cognitive mapping models against observed neuronal dynamics.

This study investigates how neural representations in the ventral hippocampus (vCA1) change during fear memory tasks and finds that representational similarity in vCA1 supports faster context retrieval.

This study shows that in a mouse model of early Alzheimer's disease, grid cells in the medial entorhinal cortex show impaired spatial coding, coinciding with early Aβ fibril deposition and spatial memory deficits.

This study investigates how the thalamic head direction system adapts to environmental cues through dynamic population dynamics and memory mechanisms.

This study shows that long-term changes in the CA1 spatial code maintain the relative structure of contextual representation over weeks.

The paper shows that DG-CA3 circuitry is essential for maintaining latent information representations in the hippocampus during navigation.

This study shows that environmental deformations cause dynamic shifts in grid cell spatial metrics, contributing to the appearance of rescaling.
