JetBall Dome
JetBall Virtual Reality System for mice with Dome can be used with mice to investigate brain functions during decision making. This is a worldwide unique product with a TFT surround monitor system and a spherical treadmill with optional operant devices. The JetBall, an air cushioned spherical treadmill allows a restrained animal to navigate in a virtual world. Brain function can be examined with electrophysiological, imaging and optogenetic methods while the animal performs behavioural tasks employing navigation, cognition, learning, or memory.
- A quarter-sphere mirror reflects the warped image from a projector onto a spherical dome screen
- Larger surface for presenting virtual reality
- Seamless display
- Predefined experiments or create your own ones with our software
- Data transfer system to combine JetBall data with external data.
Package contains,
120cm dome with stand, projector, spherical mirror, spherical treadmill with stand (Ball Holder, two balls), Dual XY-Motion Sensor, movable rack, computer (pre-installed: PhenoSoft Control, PhenoSoft Schedule, PhenoSoft VR, Virtual Corridor 2 m), control monitor, keyboard, computer mouse, power supply unit, pressure regulator system (compressor is not included). The package includes one Ball Holder. Also useable as a stand-alone product without a virtual reality system (two balls included).
