A memory model of rodent spatial navigation in which place cells are memories arranged in a grid and grid cells are non-spatial [PDF]

open access: goldeLife
A 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 ...

Orientation Invariant Sensorimotor Object Recognition Using Cortical Grid Cells [PDF]

open access: yesFrontiers 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.

Grid cells, border cells, and discrete complex analysis [PDF]

open access: yesFrontiers 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 ...

Deep Learning-Emerged Grid Cells-Based Bio-Inspired Navigation in Robotics [PDF]

open access: yesSensors
Grid cells in the brain’s entorhinal cortex are essential for spatial navigation and have inspired advancements in robotic navigation systems. This paper first provides an overview of recent research on grid cell-based navigation in robotics, focusing on

Saccade Velocity Driven Oscillatory Network Model of Grid Cells [PDF]

open access: yesFrontiers 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.

Place-cell capacity and volatility with grid-like inputs

open access: goldeLife, 2021
What factors constrain the arrangement of the multiple fields of a place cell? By modeling place cells as perceptrons that act on multiscale periodic grid-cell inputs, we analytically enumerate a place cell’s repertoire – how many field arrangements it ...

During hippocampal inactivation, grid cells maintain synchrony, even when the grid pattern is lost [PDF]

open access: yeseLife, 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.

Learning place cells, grid cells and invariances with excitatory and inhibitory plasticity. [PDF]

open access: yesElife, 2018
Neurons in the hippocampus and adjacent brain areas show a large diversity in their tuning to location and head direction, and the underlying circuit mechanisms are not yet resolved.

Modeled grid cells aligned by a flexible attractor [PDF]

open access: yeseLife
Entorhinal grid cells implement a spatial code with hexagonal periodicity, signaling the position of the animal within an environment. Grid maps of cells belonging to the same module share spacing and orientation, only differing in relative two ...

Inferring circuit mechanisms from sparse neural recording and global perturbation in grid cells [PDF]

open access: yeseLife, 2018
A goal of systems neuroscience is to discover the circuit mechanisms underlying brain function. Despite experimental advances that enable circuit-wide neural recording, the problem remains open in part because solving the ‘inverse problem’ of inferring ...
