Robust and efficient coding with grid cells. [PDF]
PLoS Comput Biol, 2018 The neuronal code arising from the coordinated population activity of grid cells in the rodent entorhinal cortex can uniquely represent space across large distances but the precise conditions for efficient coding are unknown.

Probabilistic Learning by Rodent Grid Cells. [PDF]
PLoS Comput Biol, 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

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.

Grid Cells Encode Local Positional Information. [PDF]
Curr Biol, 2017 The brain has an extraordinary ability to create an internal spatial map of the external world [1]. This map-like representation of environmental surroundings is encoded through specific types of neurons, located within the hippocampus and entorhinal cortex, which exhibit spatially tuned firing patterns [2, 3].

Locations in the Neocortex: A Theory of Sensorimotor Object Recognition Using Cortical Grid Cells. [PDF]
Front Neural Circuits, 2019 The neocortex is capable of modeling complex objects through sensorimotor interaction but the neural mechanisms are poorly understood. Grid cells in the entorhinal cortex represent the location of an animal in its environment, and this location is ...

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.

Selforganization of modular activity of grid cells. [PDF]
Hippocampus, 2017 A unique topographical representation of space is found in the concerted activity of grid cells in the rodent medial entorhinal cortex. Many among the principal cells in this region exhibit a hexagonal firing pattern, in which each cell expresses its own
