Experiments versus Theory. A) Figure adapted from . For different environments (black dots), small spatial correlation exists between place maps, and the rates can vary drastically (as measured by the rate overlap). Returning to the initial environment (blue circles) retrieves the old map with only slight changes to the rates. B) In simulations, large-scale, incoherent translations and rotations (black dots) of grid modules induce global remapping. In the control condition (return to the original environment, blue dots), noise was added to the place cell firing patterns, resembling the trial-to-trial variance of experiments.
