Grid cells in the medial entorhinal cortex (MEC) are part of an environment-independent spatial coordinate system. To determine how information about location, direction, and distance is integrated in the grid-cell network, we recorded from each principal cell layer of MEC in rats that explored two-dimensional environments. Whereas layer II was predominated by grid cells, grid cells colocalized with head-direction cells and conjunctive grid × head-direction cells in the deeper layers. All cell… 
Entorhinal Grid Cells and the Representation of Space
TLDR
Observations suggest that, despite the differential hippocampal and neocortical connections of different layers of the MEC, the area operates as an integrated unit, with significant interlaminar interaction between cells with different functional properties.
Speed cells in the medial entorhinal cortex
TLDR
It is shown that running speed is represented in the firing rate of a ubiquitous but functionally dedicated population of entorhinal neurons distinct from other cell populations of the local circuit, such as grid, head-direction and border cells.
Representation of Geometric Borders in the Entorhinal Cortex
TLDR
The existence of an entorhinal cell type that fires when an animal is close to the borders of the proximal environment is reported, and border cells may be instrumental in planning trajectories and anchoring grid fields and place fields to a geometric reference frame.
Topography of Head Direction Cells in Medial Entorhinal Cortex
Ten Years of Grid Cells.
TLDR
The aim of this review is to summarize what the authors know about grid cells and point out where the knowledge is still incomplete.
A Generalized Linear Model of a Navigation Network
TLDR
The results indicate that MEC neurons form a local interacting network to support spatial information representations and suggest an explanation for their complex temporal properties.
Transformation of the head-direction signal into a spatial code
TLDR
It is reported that activity of HD neurons are influenced by the ambulatory constraints imposed upon the animal by the boundaries of the explored environment, leading to spurious spatial information.
Grid cells encode local head direction
TLDR
It is shown that individual firing fields of pure grid cells are tuned to multiple head directions, with the preferred sets of directions differing between fields.
The Preferred Directions of Conjunctive Grid X Head Direction Cells in the Medial Entorhinal Cortex Are Periodically Organized
TLDR
This work derives and test a key prediction of one attractor network path integration mechanism and provides the first neural evidence of a nonuniform structure in the directional preferences of any head direction representation found in the brain.
Object-vector coding in the medial entorhinal cortex
TLDR
Observations show that object locations are integrated in metric representations of self-location, with specific subsets of MEC neurons encoding vector relationships to individual objects.

Microstructure of a spatial map in the entorhinal cortex
TLDR
The dorsocaudal medial entorhinal cortex (dMEC) contains a directionally oriented, topographically organized neural map of the spatial environment, whose key unit is the ‘grid cell’, which is activated whenever the animal's position coincides with any vertex of a regular grid of equilateral triangles spanning the surface of the environment.
A Spin Glass Model of Path Integration in Rat Medial Entorhinal Cortex
TLDR
A symmetric, locally connected neural network, or spin glass model, that spontaneously produces a hexagonal grid of activity bumps on a two-dimensional sheet of units is described that supports the conjecture that an attractor network in dMEC may be the source of path integration information afferent to hippocampus.
Deciphering the hippocampal polyglot: the hippocampus as a path integration system.
TLDR
A hypothesis of how the path integration system may operate at the neuronal level is proposed, and it appears that viewpoint-specific visual information becomes secondarily bound to this structure by associative learning.

TLDR
The model offers a specific one-dimensional example of a computational mechanism in which a truly world-centered representation can be derived from observer-centered sensory inputs by integrating self-motion information.
Spatial Representation in the Entorhinal Cortex
TLDR
Precise positional modulation was not observed more ventromedially in the entorhinal cortex or upstream in the postrhinal cortex, suggesting that sensory input is transformed into durable allocentric spatial representations internally in the dorsocaudal medial entorHinal cortex.
Head-direction cells in the rat posterior cortex
TLDR
There may be a simple association between movement and head-directionality that serves to transform the egocentric movement representation in the neocortex into an allocentric directional representations in the periallocortex.
Dual phase and rate coding in hippocampal place cells: Theoretical significance and relationship to entorhinal grid cells
TLDR
The hypothesis that hippocampal pyramidal cells encode information by their phase of firing relative to the theta rhythm of the EEG is reviewed and a model of the firing of the recently discovered “grid cells” in entorhinal cortex as part of a path‐integration system is proposed.
The positional firing properties of medial entorhinal neurons: description and comparison with hippocampal place cells
TLDR
The positional firing of MEC cells is more “sensory bound” than hippocampal cells, and the ability to discriminate different environments, while present in the hippocampus, is not yet present in its input from MEC.
Place cells, head direction cells, and the learning of landmark stability
TLDR
It appears that the strength of cue control over place cells and head direction cells depends on the rat's learned perception of the stability of the cues.
