Abstract

A sense of place The ability to find one's way depends on the brain's ability to integrate information about location, direction and distance. Recent advances have pointed to 'grid cells' in the brain's entorhinal cortex as one component of the mechanism for calculating position, but the neuronal network computations responsible for spatial navigation and spatial memory formation are not understood. Experiments in rats tasked to track down their food in changing environments now reveal two distinct codes for memory representation in the hippocampus. The formation of statistically independent representations in hippocampal place cells ('remapping') is invariably preceded by a coherent migration of the corresponding ensemble maps in the entorhinal cortex. This allows an animal's position to be represented and updated by the same translation mechanism as it encounters different environments.
