Why a new maze design? – Because you asked for user-friendly mazes at the price of consumables. Voila! 

Foam mazes and cages are designed for the Mobile HomeCage Large or Mobile HomeCage Large with tracking capability. To minimize shipping costs, we deliver them disassembled. But don’t worry: putting the mazes together is simpler than ever. Gluing is no longer required.

Currently, we offer these four options: a simple round cage, T-maze, donut-maze, and a brand new sociability maze. The wall height for all mazes is 40 mm. For the cages, there are two options for wall height: 40 mm and 70 mm.

The bases of mazes and cages are made of a foam material that may absorb smells and fluids. We recommend using one foam maze or cage per mouse. However, the same cage may be used during multiple experiments. Mice like walking on the foam surface as it provides a better grip compared to carbon fiber. The foam surface is particularly well-suited for juvenile mice.

What to do about locomotion tracking? Not to worry: the foam mazes and cages have magnets built into the bottom. Thus, it is possible to use Neurotar’s locomotion tracking solution while working with any of the foam mazes or cages.


Our adaptation of a classical T-maze has two return arms and doors at the end of each side corridor. This maze allows implementing spatial learning and memory tasks under head-fixation conditions. We recommend combining with the lick port and/or air puff for reinforcement and with Neurotar’s tracking hardware and software for locomotion tracking.

Donut maze

The donut maze is a circular, linear track. While navigating the maze, the mouse can learn to recognize a target location from a visual or tactile cue. Learning can be reinforced by using a lick port. A donut maze combined with the locomotion tracking can be used for imaging and recording hippocampal place cells in the Mobile HomeCage Large.

Sociability maze

The sociability maze is designed to facilitate sociability tests in the Mobile HomeCage Large: it consists of a cage with two symmetrical chambers for housing “companion” mice. Since the chambers are located outside the cage, they don’t change the cage’s geometry. Why is this important? – If you place a chamber with a second mouse inside the cage, there will be a corner and, with it, a bias. Does the head-fixed mouse favor the second mouse, or does it favor a cozy space behind the chamber? No such dilemma in our sociability maze. If you need to keep one chamber empty, remember to add a weight roughly equivalent to the weight of the “companion” mouse in the opposite chamber. Neglecting to do so may impede flotation.

Foam cage

Why use the foam cage when there is an ultralightweight carbon fiber cage which is reusable and trackable? There are several reasons to opt for the foam cage:

  • It costs a fraction of the carbon fiber cage price;
  • At this price, one can afford to have an individual cage for each test animal;
  • Mice like walking on the foam surface: it provides better grip and feels warmer;
  • Foam cages are lighter, which is crucial for juvenile mice.

Set composition

  • Fifteen(15) two-layer foam bases pre-assembled with plastic magnet holders;
  • Six (6) neodymium magnets;
  • Three (3) plastic walls for creating an external cage barrier and three (3) set of internal barriers for creating mazes (when applicable);
  • Clips and stickers for attaching the internal barriers.

Using these parts allows fully assembling three cages or mazes and leaving the remaining 12 base parts as spares. If you are using all fifteen bases simultaneously, remember to clean and disinfect the walls and internal barriers before using them for a different mouse.

Technical characteristics

  • Size: Ø 325 X 40 mm (diameter of the internal cage in the social maze is Ø 234 mm)
  • Material: Depron 3mm thick foam
  • Weight: 60-90 g/maze (assembled with magnets for locomotion tracking)
