Framing of grid cells within and beyond navigation boundaries. [PDF]
Elife, 2017 Grid cells represent an ideal candidate to investigate the allocentric determinants of the brain’s cognitive map. Most studies of grid cells emphasized the roles of geometric boundaries within the navigational range of the animal. Behaviors such as novel

Learning place cells, grid cells and invariances with excitatory and inhibitory plasticity. [PDF]
Elife, 2018 Neurons in the hippocampus and adjacent brain areas show a large diversity in their tuning to location and head direction, and the underlying circuit mechanisms are not yet resolved.

From grid cells to place cells with realistic field sizes. [PDF]
PLoS One, 2017 While grid cells in the medial entorhinal cortex (MEC) of rodents have multiple, regularly arranged firing fields, place cells in the cornu ammonis (CA) regions of the hippocampus mostly have single spatial firing fields.

Modeled grid cells aligned by a flexible attractor [PDF]
eLifeEntorhinal grid cells implement a spatial code with hexagonal periodicity, signaling the position of the animal within an environment. Grid maps of cells belonging to the same module share spacing and orientation, only differing in relative two ...

Using Grid Cells for Navigation [PDF]
Neuron, 2015 Summary Mammals are able to navigate to hidden goal locations by direct routes that may traverse previously unvisited terrain. Empirical evidence suggests that this “vector navigation” relies on an internal representation of space provided by the ...

Inferring circuit mechanisms from sparse neural recording and global perturbation in grid cells [PDF]
eLife, 2018 A goal of systems neuroscience is to discover the circuit mechanisms underlying brain function. Despite experimental advances that enable circuit-wide neural recording, the problem remains open in part because solving the ‘inverse problem’ of inferring ...

Neural Dynamics Indicate Parallel Integration of Environmental and Self-Motion Information by Place and Grid Cells [PDF]
Frontiers in Neural Circuits, 2019 Place cells and grid cells in the hippocampal formation are thought to integrate sensory and self-motion information into a representation of estimated spatial location, but the precise mechanism is unknown.

Conformal Isometry of Lie Group Representation in Recurrent Network of Grid Cells [PDF]
NeurReps, 2022 The activity of the grid cell population in the medial entorhinal cortex (MEC) of the mammalian brain forms a vector representation of the self-position of the animal.

Annual Review of Neuroscience, 2016 The medial entorhinal cortex (MEC) creates a neural representation of space through a set of functionally dedicated cell types: grid cells, border cells, head direction cells, and speed cells. Grid cells, the most abundant functional cell type in the MEC, have hexagonally arranged firing fields that tile the surface of the environment.
