Grid-cell representations in mental simulation
eLife, 2016 Anticipating the future is a key motif of the brain, possibly supported by mental simulation of upcoming events. Rodent single-cell recordings suggest the ability of spatially tuned cells to represent subsequent locations.

Modeled grid cells aligned by a flexible attractor [PDF]
eLifeEntorhinal 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 ...

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.

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

How Does the Modular Organization of Entorhinal Grid Cells Develop? [PDF]
Frontiers in Human Neuroscience, 2014 The entorhinal-hippocampal system plays a crucial role in spatial cognition and navigation. Since the discovery of grid cells in layer II of medial entorhinal cortex (MEC), several types of models have been proposed to explain their development and ...

Neural Dynamics Indicate Parallel Integration of Environmental and Self-Motion Information by Place and Grid Cells [PDF]
Frontiers in Neural Circuits, 2019 Place cells and grid cells in the hippocampal formation are thought to integrate sensory and self-motion information into a representation of estimated spatial location, but the precise mechanism is unknown.

Learning Grid Cells by Predictive Coding [PDF]
Grid cells in the medial entorhinal cortex (MEC) of the mammalian brain exhibit a strikingly regular hexagonal firing field over space. These cells are learned after birth and are thought to support spatial navigation but also more abstract computations.
