eLifeAlthough grid cells are one of the most well-studied functional classes of neurons in the mammalian brain, whether there is a single orientation and spacing value per grid module has not been carefully tested. We analyze a recent large-scale recording of

Representation of nonspatial and spatial information in the lateral entorhinal cortex
Frontiers in Behavioral Neuroscience, 2011 Some theories of memory propose that the hippocampus integrates the individual items and events of experience within a contextual or spatial framework.

Frontiers in Synaptic Neuroscience, 2018 Spatial memory processing requires functional interaction between the hippocampus and the medial entorhinal cortex (MEC). The grid cells of the MEC are most abundant in layer II and rely on a complex network of local inhibitory interneurons to generate ...

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 response properties still defy explanation.

Simulating streamer discharges in 3D with the parallel adaptive Afivo framework [PDF]
, 2017 We present an open-source plasma fluid code for 2D, cylindrical and 3D simulations of streamer discharges, based on the Afivo framework that features adaptive mesh refinement, geometric multigrid methods for Poisson's equation, and OpenMP parallelism. We

Fully Convolutional Neural Networks for Dynamic Object Detection in Grid Maps
, 2017 Grid maps are widely used in robotics to represent obstacles in the environment and differentiating dynamic objects from static infrastructure is essential for many practical applications. In this work, we present a methods that uses a deep convolutional

On the optimality of grid cells
CoRR, 2016 Grid cells, discovered more than a decade ago [5], are neurons in the brain of mammals that fire when the animal is located near certain specific points in its familiar terrain. Intriguingly, these points form, for a single cell, a two-dimensional triangular grid, not unlike our Figure 3.

Disrupting the Grid Cells’ Need for Speed [PDF]
Neuron, 2016 Hinman et al. demonstrate the presence of two speed signals in the rodent medial entorhinal cortex that are differentially affected by muscimol inactivation of medial septum. The results reveal important constraints on several computational models of grid cell firing.

GABAA Receptor Subunit α3 in Network Dynamics in the Medial Entorhinal Cortex
Frontiers in Systems Neuroscience, 2019 Layer II of the medial entorhinal cortex (MEC LII) contains the largest number of spatially modulated grid cells and is one of the first regions in the brain to express Alzheimer’s disease (AD)-related pathology.
