The PhenoSys Double Disk Treadmill offering a unique solution that fuses the stability of linear treadmill and the exploration flexibility of a spherical treadmill . Its innovative two-disk design provides animals with the free, multi-directional movement crucial for spatial exploration, while simultaneously ensuring the stability needed for consistent running paradigms. This system enhances experimental precision by giving researchers full control over execution and allowing real-time adjustments based on the animal’s natural responses. It’s an ideal platform for investigating complex animal behavior under highly dynamic and flexible conditions.
DoubleDisk Treadmill was invented by Mackenzie Mathis and her team at Harvard University and EPFL (“Hausmann, S., Kane, G., & Mathis, M.W. A new mini-VR and dual-wheel platform for closed-loop motor learning and adaptation in mice. FENS 2022 Poster Session. Paris, FR.”)
Features

Zero-point sensor for synchronization, used to determine the degree of disk rotation.
Brakes to stop movement of the disk, as a trigger to gain control of the animal’s behavior.
Hardware Setup: movable rack, computer with pre-installed software Virtual Corridor 2 m, control monitor, keyboard & mouse
Power supply unit & pressure regulator system
Interactive add-ons like reward delivery systems, whisker stimulation, audio and odor stimuli and additional customizable modules
Predefined experiments or create your own with our software (1 complementary custom paradigm provided with the system)
DoubleDisk-TFT: High-Resolution Precision
The DoubleDisk-TFT utilizes a 270° TFT surround monitor system to create a high-resolution, cylindrical virtual environment around the animal.
This well-established and most popular display setup delivers crisp visuals with high-contrast image and luminescence, horizontal display, providing an excellent platform for precise visual stimulus presentation.
TFT Monitor Ring: 6 TFT sub-units forming 270° viewing angle
Excellent Clarity: Optimized for high luminescence & contrast .
DoubleDisk-Dome: Expansive Immersion
The DoubleDisk-Dome employs a quarter-sphere mirror projection system that reflects warped images from a projector onto a spherical dome screen.
This creates a larger, seamless, and highly immersive virtual environment, offering an expansive field of view.
Mirror Projection Dome: Creates a wide, immersive field of view
Seamless Immersion: Eliminates visual discontinuities for a more naturalistic experience.
Top Cut-out Option: Available for enhanced vertical access special imaging setups like 2P-microscopy
.
