The Virtual Reality ServoBall is based on an active, servo-driven spherical treadmill. It allows a video-tracked freely moving animal (e.g. mouse, rat) to navigate in virtual space. The ServoBall can be used for investigating navigation, cognition, learning and memory. A wide range of brain circuits can be stimulated through diverse operant protocols and multi-modal sensory stimulation. For unrestrained animals, even 24-hour experimentation is possible.
The ServoBall is made available in cooperation with Humboldt University, Berlin.
