Using Grid Cells for Navigation [PDF]
Neuron, 2015 Mammals are able to navigate to hidden goal locations by direct routes that may traverse previously unvisited terrain. Empirical evidence suggests that this "vector navigation" relies on an internal representation of space provided by the hippocampal formation.

Recurrent amplification of grid‐cell activity [PDF]
Hippocampus, 2020 AbstractHigh‐level cognitive abilities such as navigation and spatial memory are thought to rely on the activity of grid cells in the medial entorhinal cortex (MEC), which encode the animal's position in space with periodic triangular patterns. Yet the neural mechanisms that underlie grid‐cell activity are still unknown.

eLife, 2016 Neurons of the medial entorhinal cortex (MEC) provide spatial representations critical for navigation. In this network, the periodic firing fields of grid cells act as a metric element for position.

Entorhinal Neurons Exhibit Cue Locking in Rodent VR
Frontiers in Cellular Neuroscience, 2019 The regular firing pattern exhibited by medial entorhinal (mEC) grid cells of locomoting rodents is hypothesized to provide spatial metric information relevant for navigation.

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 ...

A Framework for Intelligence and Cortical Function Based on Grid Cells in the Neocortex
Frontiers in Neural Circuits, 2019 How the neocortex works is a mystery. In this paper we propose a novel framework for understanding its function. Grid cells are neurons in the entorhinal cortex that represent the location of an animal in its environment.

Excitatory Microcircuits within Superficial Layers of the Medial Entorhinal Cortex
Cell Reports, 2017 The distinctive firing pattern of grid cells in the medial entorhinal cortex (MEC) supports its role in the representation of space. It is widely believed that the hexagonal firing field of grid cells emerges from neural dynamics that depend on the local

A Generalized Linear Model of a Navigation Network
Frontiers in Neural Circuits, 2020 Navigation by mammals is believed to rely on a network of neurons in the hippocampal formation, which includes the hippocampus, the medial entorhinal cortex (MEC), and additional nearby regions.
