PhenoSys qOMR

The optomotor response (OMR) is a reflex used to assess visual function in rodents. The PhenoSys qOMR (mice) and the qOMR-XT (rats) are unique systems that objectively measure the OMR with minimal experimenter effort. It employs a virtual stimulation cylinder that continuously aligns with the animal’s head position. Based on real-time head tracking, quantitative OMR measurements automatically provide visual acuity and contrast sensitivity.

• Simple, robust, and non-invasive test to examine vision in rodents
• Fully automated measurement and analysis: no manual positioning of the stimulus, no specially trained experimenter required, time and cost effective, and unbiased
• As a reflex, OMR measurements do not require animal training
• Freely behaving animals, no surgery, no fixation
• Flexible, user-friendly experimental design and data handling.
• Calibrated 4 screen environment for presenting the virtual stimulation sphere
• Elevated central platform for placing the unrestrained animal
• Top and bottom mirror to create an illusion of infinite depth
• IR-camera with adjustable IR-illumination for automated head tracking.
