Experience-dependent rescaling of entorhinal grids.

Caswell Barry¹, Robin Hayman, Neil Burgess, Kathryn J Jeffery.

Abstract

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. Thus grid scale reflects an interaction between intrinsic, path-integrative calculation of location and learned associations to the external environment.
