    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.

    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.

    Framing of grid cells within and beyond navigation boundaries

    Francesco Savelli et al.
    Grid-cell maps can be aligned to both local and remote reference frames, suggesting that they provide a metric for space beyond the navigationally accessible boundaries of the local environment.

    Grid-cell representations in mental simulation

    Jacob LS Bellmund et al.
    Functional magnetic resonance imaging performed while people imagined directions from stationary viewpoints supports theories suggesting that spatially tuned cells such as grid cells underlie mental simulation for future thinking.

    Anatomical organization of presubicular head-direction circuits

    Patricia Preston-Ferrer et al.
    Presubicular head-direction circuits are cell-type specific, with long-range projections reaching the 'grid-cell area' medial entorhinal cortex.

    Neural activity in a hippocampus-like region of the teleost pallium is associated with active sensing and navigation

    Haleh Fotowat et al.
    Sparse firing in a hippocampus-like structure of the teleost telencephalon is linked to spatial navigation and active sensing.

    Interactions between stimulus and response types are more strongly represented in the entorhinal cortex than in its upstream regions in rats

    Eun-Hye Park et al.
    Goal-directed interaction with objects and spatial navigation are subserved by the perirhinal-lateral entorhinal networks and the postrhinal-medial entorhinal networks, respectively, with action-based functional differentiation more strongly represented in the entorhinal cortex than its upstream.

    Decision and navigation in mouse parietal cortex

    Michael Krumin et al.
    When mice use vision to choose their trajectories, a large fraction of parietal cortex activity can be precisely predicted from navigational attributes such as spatial position and heading.

    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.

    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.
