Optimal Population Codes for Space: Grid Cells Outperform Place Cells [PDF]
, 2012 Rodents use two distinct neuronal coordinate systems to estimate their position: place fields in the hippocampus and grid fields in the entorhinal cortex.

How to build a grid cell [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2014 Neurons in the medial entorhinal cortex fire action potentials at regular spatial intervals, creating a striking grid-like pattern of spike rates spanning the whole environment of a navigating animal. This remarkable spatial code may represent a neural map for path integration.

eLife, 2018 Computational models postulate that head-direction (HD) cells are part of an attractor network integrating head turns. This network requires inputs from visual landmarks to anchor the HD signal to the external world.

eLife, 2019 Grid cells in the medial entorhinal cortex (MEC) encode position using a distributed representation across multiple neural populations (modules), each possessing a distinct spatial scale.

Streamline integration as a method for structured grid generation in X-point geometry [PDF]
, 2018 We investigate structured grids aligned to the contours of a two-dimensional flux-function with an X-point (saddle point). Our theoretical analysis finds that orthogonal grids exist if and only if the Laplacian of the flux-function vanishes at the X ...

Spatialization of Time in the Entorhinal-Hippocampal System
Frontiers in Behavioral Neuroscience, 2022 The functional role of the entorhinal-hippocampal system has been a long withstanding mystery. One key theory that has become most popular is that the entorhinal-hippocampal system represents space to facilitate navigation in one’s surroundings.

Using Grid Cells for Navigation [PDF]
Neuron, 2015 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 hippocampal formation.

Recurrent amplification of grid‐cell activity [PDF]
Hippocampus, 2020 AbstractHigh‐level cognitive abilities such as navigation and spatial memory are thought to rely on the activity of grid cells in the medial entorhinal cortex (MEC), which encode the animal's position in space with periodic triangular patterns. Yet the neural mechanisms that underlie grid‐cell activity are still unknown.

Does the Entorhinal Cortex use the Fourier Transform?
Frontiers in Computational Neuroscience, 2013 Some neurons in the entorhinal cortex (EC) fire bursts when the animal occupies locations organized in a hexagonal grid pattern in their spatial environment.

A Spatial Location Representation Method Incorporating Boundary Information
Applied Sciences, 2023 In response to problems concerning the low autonomous localization accuracy of mobile robots in unknown environments and large cumulative errors due to long time running, a spatial location representation method incorporating boundary information (SLRB ...
