Barnes Maze

Ideal for testing spatial learning and memory, the Barnes Maze motivates animals to hide from the bright, open platform by finding the small, dark “escape box.” Animals learn the escape box’s location without the stress of swimming or food deprivation and false escape boxes remove the possibility of inadvertent cues. San Diego Instruments (SDI) designed its maze to be easy to use, clean and transport. With a variety of color options, the maze adjusts to fit a wide range of experiments and is compatiable with ANY-Maze Video Tracking. The maze comes in both rat and mouse models and includes 20 explorations holes, 20 false escape boxes and one escape box.
