Grid cells and cortical representation [PDF]
Nature 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

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.

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, 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.

Robust and efficient coding with grid cells. [PDF]
PLoS Comput Biol, 2018 Abstract The neuronal code arising from the coordinated population activity of grid cells in the rodent entorhinal cortex can uniquely represent space across large distances but the precise conditions for efficient coding are unknown. Here we present a number-theoretic analysis of grid coding and derive an upper bound on the distance ...

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.

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.

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.

Framing the grid: effect of boundaries on grid cells and navigation [PDF]
The Journal of Physiology, 2016 AbstractCells in the mammalian hippocampal formation subserve neuronal representations of environmental location and support navigation in familiar environments. Grid cells constitute one of the main cell types in the hippocampal formation and are widely believed to represent a universal metric of space independent of external stimuli.

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 ...
