The self-organization of grid cells in 3D
eLife, 2015 Do we expect periodic grid cells to emerge in bats, or perhaps dolphins, exploring a three-dimensional environment? How long will it take? Our self-organizing model, based on ring-rate adaptation, points at a complex answer.

Probabilistic Learning by Rodent Grid Cells. [PDF]
PLoS Computational Biology, 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

Frontiers in Computational Neuroscience, 2023 IntroductionVisual-spatial perception is a process for extracting the spatial relationship between objects in the environment. The changes in visual-spatial perception due to factors such as the activity of the sympathetic nervous system (hyperactivation)

Multi-Scale Extension in an Entorhinal-Hippocampal Model for Cognitive Map Building
Frontiers in Neurorobotics, 2021 Neuroscience research shows that, by relying on internal spatial representations provided by the hippocampus and entorhinal cortex, mammals are able to build topological maps of environments and navigate.

Place Cells, Grid Cells, and Memory [PDF]
Cold Spring Harbor Perspectives in Biology, 2015 The hippocampal system is critical for storage and retrieval of declarative memories, including memories for locations and events that take place at those locations. Spatial memories place high demands on capacity. Memories must be distinct to be recalled without interference and encoding must be fast.

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.

Neural Computation, 2022 Grid cells play a principal role in enabling mammalian cognitive representations of ambient environments. The key property of these cells—the regular arrangement of their firing fields—is commonly viewed as means for establishing spatial scales or encoding specific locations.
