The Horizontal Ladder test is a motor and coordination test for evaluating skilled walking for mice and rats. Steps are counted and classified as either correct/functional paw placement, a slip, or a miss. Fore & hind-limb coordination can be assessed further by removing individual ladder rungs to evaluate how the rodent targets individual rungs.
The animals are required to walk on a horizontal rung ladder spontaneously with varied spacing between rungs. The MazeEngineers horizontal ladder allows for the removal of individual rungs. Flexibly made to clamp to end plates to allow for aversive or rewarded locomotion. Clear walls allow for easy video recording.
The Y maze is similar to the T maze, except with three arms at 120 degrees to each other. The rodent or mouse starts at the end of one arm, then chooses between the other two. Spontaneous alternation is measured to demonstrate learning.
The Y-maze is often preferred to the T-maze because gradual turns decrease learning time as compared to the sharp turns of the T-maze. It is also a smaller maze* to allow fewer degrees of freedom of movement, focusing the animal on the task at hand. The Y Maze can also be baited with food for rewarded alternation. Food wells are standard 1cm deep.
