    A geometric attractor mechanism for self-organization of entorhinal grid modules

    Louis Kang, Vijay Balasubramanian
    The hierarchy of entorhinal grid cell modules with constant scale ratios can self-organize through a new geometrically organized attractor mechanism.

    Velocity coupling of grid cell modules enables stable embedding of a low dimensional variable in a high dimensional neural attractor

    Noga Mosheiff, Yoram Burak
    The neural representation of position in the medial entorhinal cortex may be stabilized by synaptic connectivity across modules, which enforces coherent updates in their states.

    Environmental deformations dynamically shift the grid cell spatial metric

    Alexandra T Keinath et al.
    When a familiar environment is reshaped, the grid cell spatial code is dynamically anchored to recently encountered boundaries and changes throughout exploration with the specific movement history of the navigator.

    Spatial cell firing during virtual navigation of open arenas by head-restrained mice

    Guifen Chen et al.
    A mouse virtual reality system is presented which allows normal spatial behavior and place, grid and head-direction cell firing patterns in 2-D arenas, and is compatible with electrophysiology and multi-photon imaging.

    Replay as wavefronts and theta sequences as bump oscillations in a grid cell attractor network

    Louis Kang, Michael R DeWeese
    An experimentally supported model of grid cells naturally enables them to participate in firing sequences that encode rapid trajectories in space.

    The self-organization of grid cells in 3D

    Federico Stella, Alessandro Treves
    A computational model for the formation of neural networks of grid cells in virtual bats suggests that the highly ordered networks presumed to support spatial navigation in two dimensions cannot be routinely established in three-dimensional space.

    Meta-Research: Incidences of problematic cell lines are lower in papers that use RRIDs to identify cell lines

    Zeljana Babic et al.
    The use of Research Resource Identifiers (RRIDs) improves the proper use of cell lines in the biomedical literature.

    Navigation: Shedding light on stellate cells

    Andrew S Alexander, Michael E Hasselmo
    The relationship between grid cells and two types of neurons found in the medial entorhinal cortex has been clarified.
