The paper shows that grid and place cells in rats encode left-right alternating theta sweeps that sample the environment beyond the animal's path, suggesting an efficient spatial sampling mechanism.

This study shows that grid-cell modules remain coordinated in darkness, even when their internal position representation diverges from the animal's true position.

The paper shows that grid cell activity forms a toroidal manifold, supporting continuous attractor network dynamics in the medial entorhinal cortex.

This study compares how position, head direction, and speed are encoded in CA1 and subiculum during different navigation tasks, finding stronger mixed selectivity in subiculum.

The paper introduces Neuropixels 2.0, a high-density probe for long-term brain recordings, and demonstrates its stability across months in multiple labs and species.

The paper shows that grid cell correlation structures remain consistent across sleep and navigation, suggesting universal network states in the medial entorhinal cortex.
