The Y-maze allows animals to select between two arms based on memory or reward. Because the Y-maze’s arms have a gradual turn, animals understand the layout more quickly than a T-Maze, decreasing learning time. San Diego Instruments (SDI) also provides a MOUSE water tight Y maze. Including removable doors, and a variety of additional color options, SDI’s Y-maze adjusts to fit a wide range of experiments. San Diego Instrument’s (SDI) Y-maze is uniquely designed to be easy to use and clean as well as highly versatile.
