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.

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 ...

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.

Place Cells, Grid Cells, Attractors, and Remapping [PDF]
Neural Plasticity, 2011 Place and grid cells are thought to use a mixture of external sensory information and internal attractor dynamics to organize their activity. Attractor dynamics may explain both why neurons react coherently following sufficiently large changes to the environment (discrete attractors) and how firing patterns move smoothly from one representation to the ...

Solving navigational uncertainty using grid cells on robots [PDF]
, 2010 To successfully navigate their habitats, many mammals use a combination of two mechanisms, path integration and calibration using landmarks, which together enable them to estimate their location and orientation, or pose.

Ring Attractors as the Basis of a Biomimetic Navigation System
Biomimetics, 2023 The ability to navigate effectively in a rich and complex world is crucial for the survival of all animals. Specialist neural structures have evolved that are implicated in facilitating this ability, one such structure being the ring attractor network ...

Ontogeny of neural circuits underlying spatial memory in the rat [PDF]
, 2012 Spatial memory is a well-characterized psychological function in both humans and rodents. The combined computations of a network of systems including place cells in the hippocampus, grid cells in the medial entorhinal cortex and head direction cells ...
