Abstract

Grid cells in the medial entorhinal cortex (MEC) are part of an environment-independent spatial coordinate system. To determine how information about location, direction, and distance is integrated in the grid-cell network, we recorded from each principal cell layer of MEC in rats that explored two-dimensional environments. Whereas layer II was predominated by grid cells, grid cells colocalized with head-direction cells and conjunctive grid × head-direction cells in the deeper layers. All cell types were modulated by running speed. The conjunction of positional, directional, and translational information in a single MEC cell type may enable grid coordinates to be updated during self-motion–based navigation.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The firing of conjunctive grid cells, found in deeper layers of entorhinal cortex and in pre- and parasubiculum, is modulated by running direction.

    “The firing of ‘conjunctive’ grid cells, found in the deeper layers of entorhinal cortex6 and in pre- and parasubiculum7, is modulated by running direction6.”

  • The dependence of directional modulation on running speed is consistent with the effects of speed on the firing rate and apparent spatial organisation of grid cells.

    “The dependence of directional modulation on running speed is consistent with the effects of speed on the firing rate6,10 and apparent spatial organisation (Fig. 1d) of grid cells”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
