Fed standard chow

Fed blueberry extract

D836-4

To measure cognition in rats, ARS scientists used video imaging of a pool to track the route rats to find a submerged platform (the end point of their swim). These diagrams show the top views of the routes taken. In the trials, the rats fed the standard chow took longer to find the platform and showed little or no progress in learning. In the same water maze, rats fed the blueberry extract learned to locate the platform faster.
