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.

Unique grid cell identification of Croatian official map grids [PDF]

open access: yesJournal of Maps, 2014
The Unique Grid Cell Identification (UGCI) system was created using the Croatian cartographic map grid system as a basis for development. A short description of the Croatian map grid system is therefore provided. Cartographic map nomenclature is used to uniquely identify map sheets; e.g. grid cells.

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.

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.

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.

Does Optic Flow Explain the Firing of Grid Cells? [PDF]

open access: yes, 2011
*Problem.* Various cues such as vestibular, sensorimotor, or visual information can lead to the firing of grid cells recorded in entorhinal cortex of rats.

Does the Entorhinal Cortex use the Fourier Transform?

open access: yesFrontiers 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

open access: yesApplied 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 ...

Using 3D Voronoi grids in radiative transfer simulations [PDF]

open access: yes, 2013
Probing the structure of complex astrophysical objects requires effective three-dimensional (3D) numerical simulation of the relevant radiative transfer (RT) processes. As with any numerical simulation code, the choice of an appropriate discretization is
