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.

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.

Place cells, grid cells, and memory. [PDF]
Cold Spring Harb Perspect Biol, 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.

Frontiers in Systems Neuroscience, 2020 The brain is capable of registering a constellation of events, encountered only once, as an episodic memory that can last for a lifetime. As evidenced by the clinical case of the patient HM, memories preserving their episodic nature still depend on the ...

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.

Network mechanisms of grid cells [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2014 One of the major breakthroughs in neuroscience is the emerging understanding of how signals from the external environment are extracted and represented in the primary sensory cortices of the mammalian brain. The operational principles of the rest of the cortex, however, have essentially remained in the dark.

Place-cell capacity and volatility with grid-like inputs
eLife, 2021 What factors constrain the arrangement of the multiple fields of a place cell? By modeling place cells as perceptrons that act on multiscale periodic grid-cell inputs, we analytically enumerate a place cell’s repertoire – how many field arrangements it ...

Grid cells' need for speed [PDF]
Nature Neuroscience, 2016 Grid-firing fields of neurons in the entorhinal cortex are thought to require inputs encoding running speed. Glutamatergic projections from the medial septum may be one of the inputs that provide these speed signals.

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.

Resonating neurons stabilize heterogeneous grid-cell networks
eLife, 2021 A central theme that governs the functional design of biological networks is their ability to sustain stable function despite widespread parametric variability.
