Excitatory-Inhibitory Recurrent Dynamics Produce Robust Visual Grids and Stable Attractors

The paper trains a biologically-inspired recurrent neural network to simulate visual grid cell activity in rat V2 and finds grid-like patterns emerge robustly across different network configurations and tasks.

Sharp tuning of head direction by somatosensory fast-spiking interneurons

The paper characterizes head direction (HD) cells in the somatosensory cortex, finding that fast-spiking inhibitory neurons are sharply tuned to HD and have distinct organizational features.

Bimodal Remapping of Visual Grids

The paper identifies two classes of V2 grid cells in rats with distinct remapping properties, showing bimodal remapping and stable firing patterns during environmental changes.

Egocentric Asymmetric Coding in Sensory Cortical Border Cells

The paper identifies rotation-selective egocentric border cells in rat somatosensory and visual cortices that maintain directional tuning across environmental changes.

A compact spatial map in V2 visual cortex

The paper identifies spatially tuned neurons in the visual cortex of rats that form a spatio-visual map, independent of visual input.

A novel somatosensory spatial navigation system outside the hippocampal formation

The paper identifies spatially tuned cell types in the somatosensory cortex of foraging rats, suggesting spatial information is used for body representation outside the hippocampal formation.
