The grid code for ordered experience
Entorhinal cortical grid cells fire in a periodic pattern that tiles space, which is suggestive of a
spatial coordinate system. However, irregularities in the grid pattern as well as responses of …

Path integration maintains spatial periodicity of grid cell firing in a 1D circular track
Entorhinal grid cells are thought to provide a 2D spatial metric of the environment. In this
study we demonstrate that in a familiar 1D circular track (ie, a continuous space) grid cells …
