Optimal Population Codes for Space: Grid Cells Outperform Place Cells [PDF]

open access: yes, 2012
Rodents use two distinct neuronal coordinate systems to estimate their position: place fields in the hippocampus and grid fields in the entorhinal cortex.

Grid cells and cortical representation [PDF]

open access: yesNature Reviews Neuroscience, 2014
One of the grand challenges in neuroscience is to comprehend neural computation in the association cortices, the parts of the cortex that have shown the largest expansion and differentiation during mammalian evolution and that are thought to contribute profoundly to the emergence of advanced cognition in humans. In this Review, we use grid cells in the

Grid Cells Form a Global Representation of Connected Environments. [PDF]

open access: yes, 2015
The firing patterns of grid cells in medial entorhinal cortex (mEC) and associated brain areas form triangular arrays that tessellate the environment [1, 2] and maintain constant spatial offsets to each other between environments [3, 4].

Resonating neurons stabilize heterogeneous grid-cell networks

open access: yeseLife, 2021
A central theme that governs the functional design of biological networks is their ability to sustain stable function despite widespread parametric variability.

How to build a grid cell [PDF]

open access: yesPhilosophical 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.

Non-rhythmic head-direction cells in the parahippocampal region are not constrained by attractor network dynamics

open access: yeseLife, 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.

Velocity coupling of grid cell modules enables stable embedding of a low dimensional variable in a high dimensional neural attractor

open access: yeseLife, 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.

Recurrent amplification of grid‐cell activity [PDF]

open access: yesHippocampus, 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.

Spatialization of Time in the Entorhinal-Hippocampal System

open access: yesFrontiers 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.

Navigating by decoding grid cells: Investigating the role of entorhinal grid cells through computational modeling at the intersection of neuroscience and artificial intelligence [PDF]

open access: yes, 2019
Ever since grid cells were discovered in the mammalian entorhinal cortex over a decade ago, the striking representation of space generated by these neurons has offered a peek at the inner workings of navigational processes and possibly other high-level ...
