Image Number D836-2 To measure cognition in rats, ARS scientists used video imaging of a pool to track the route rats took to find a submerged platform (the end point of their swim).  This diagram of the top view of a later trial of a rat fed standard chow shows that the rat improved little or not at all in learning how to locate the platform.
