The Elevated Zero-Maze is sometimes preferred to the Elevated Plus-Maze, because it offers the animal a smoother transition from closed to open arms.
In the Elevated Plus-Maze, this transition implies that the animal actively turns to one of the two open arms, while in the Elevated Zero-Maze the transition occurs more spontaneously, as the animal simply keeps walking on the maze.
