Grid cells in an inhibitory network
Nature Neuroscience, 2014Grid cells have been proposed to reflect competitive interactions in inhibitory neural networks. Experimental results obtained using optogenetics to identify spikes emitted specifically by parvalbumin interneurons now constrain the mechanisms by which such networks could give rise to grid cells.

Navigating with distorted grid cells
The 2018 Conference on Artificial Life, 2018Grid cells in the hippocampal formation are a valuable system to study both for neuroscientists and for neural network researchers, as these neurons present both a window into higher-level cognitiv...

Challenges for Place and Grid Cell Models
2021This chapter gives a short overview of computational models dealing with two fundamental building blocks in spatial cognition: grid and place cells, and of the open issues such models may help address.

A hexagonal Fourier model of grid cells
Hippocampus, 2018AbstractGrid cells in rat medial entorhinal cortex are widely thought to play a major role in spatial behavior. However, the exact computational role of the population of grid cells is not known. Here we provide a descriptive model, which nonetheless considers biologically feasible mechanisms, whereby the grid cells are viewed as a two‐dimensional ...

A neuromorphic VLSI grid cell system
2012 IEEE International Symposium on Circuits and Systems, 2012Neurons in the medial entorhinal cortex of rats have been found to respond in a two-dimensional hexagonal “grid” pattern anchored to the environment. “Grid cells” with different spatial frequencies are thought to contribute to the creation of unimodal “place” cell responses useful for spatial navigation.

The transformation from grid cells to place cells is robust to noise in the grid pattern.
Hippocampus, 2015Spatial navigation in rodents has been attributed to place-selective cells in the hippocampus and entorhinal cortex. However, there is currently no consensus on the neural mechanisms that generate the place-selective activity in hippocampal place cells or entorhinal grid cells.
