Grid cells, border cells, and discrete complex analysis [PDF]
Frontiers in Computational Neuroscience, 2023 We propose a mechanism enabling the appearance of border cells—neurons firing at the boundaries of the navigated enclosures. The approach is based on the recent discovery of discrete complex analysis on a triangular lattice, which allows constructing ...

During hippocampal inactivation, grid cells maintain synchrony, even when the grid pattern is lost [PDF]
eLife, 2019 The grid cell network in the medial entorhinal cortex (MEC) has been subject to thorough testing and analysis, and many theories for their formation have been suggested.

Orientation Invariant Sensorimotor Object Recognition Using Cortical Grid Cells [PDF]
Frontiers in Neural Circuits, 2022 Grid cells enable efficient modeling of locations and movement through path integration. Recent work suggests that the brain might use similar mechanisms to learn the structure of objects and environments through sensorimotor processing.

Computational Models of Grid Cells [PDF]
Neuron, 2011 Grid cells are space-modulated neurons with periodic firing fields. In moving animals, the multiple firing fields of an individual grid cell form a triangular pattern tiling the entire space available to the animal. Collectively, grid cells are thought to provide a context-independent metric representation of the local environment.

A memory model of rodent spatial navigation in which place cells are memories arranged in a grid and grid cells are non-spatial [PDF]
eLifeA theory and neurocomputational model are presented that explain grid cell responses as the byproduct of equally dissimilar hippocampal memories. On this account, place and grid cells are best understood as the natural consequence of memory encoding and ...

Selforganization of modular activity of grid cells [PDF]
Hippocampus, 2017 A unique topographical representation of space is found in the concerted activity of grid cells in the rodent medial entorhinal cortex. Many among the principal cells in this region exhibit a hexagonal firing pattern, in which each cell expresses its own

Saccade Velocity Driven Oscillatory Network Model of Grid Cells [PDF]
Frontiers in Computational Neuroscience, 2019 Grid cells and place cells are believed to be cellular substrates for the spatial navigation functions of hippocampus as experimental animals physically navigated in 2D and 3D spaces.

Probabilistic Learning by Rodent Grid Cells. [PDF]
PLoS Comput Biol, 2016 Mounting evidence shows mammalian brains are probabilistic computers, but the specific cells involved remain elusive. Parallel research suggests that grid cells of the mammalian hippocampal formation are fundamental to spatial cognition but their diverse response properties still defy explanation.

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 ...
