Virtual Reality for uncovering neural dynamics in decision making.

VR systems - new possibilities in neuroscience.

We provide worldwide unique VR systems for combining animal behaviour with neuroscience. Our JetBall spherical treadmills allow a mouse or rat to navigate and perform behavioural tasks in a virtual space, while the brain can be examined with optogenetic, electrophysiological, or advanced imaging methods.

VR allows more flexible modifications of experimental environments and conditions than real mazes, e.g. hiding and switching landmarks automatically, teleporting of an animal to a new task or by using endless mazes.

We have spent years developing and refining our JetBall and other systems for mice and rats in cooperation with Berlin-based neuroscience groups. Utilize our experience for your own research to explore new horizons in neurobiology.

Benefits from our virtual environments:

  • Use our predefined virtual JetBall mazes for learning, memory, cognition and navigation tasks: 2m-Corridor, Endless-Corridor, T-Maze, Plus-Maze, Y-Maze, 1m-Open Field.
  • Create your own virtual mazes with our flexible software: place landmarks variable in size and shape appearing and disappearing at defined times, run different mazes as test batteries in a single sequence without removing the animal from the top of the ball, or uncouple the virtual reality and the actual movement of the animal.
  • Extend the JetBall system with our optional operant modules for combining them with virtual scenes.
  • Relay experimental data from the JetBall via our data transfer system to any additional experimental computer for synchronising data streams.
