Experience-dependent rescaling of entorhinal grids

Caswell Barry , Robin Hayman , Neil Burgess & Kathryn J Jeffery

The firing pattern of entorhinal 'grid cells' is thought to provide an intrinsic metric for space. We report a strong experience-dependent environmental influence: the spatial scales of the grids (which are aligned and have fixed relative sizes within each animal) vary parametrically with changes to a familiar environment's size and shape.
