The optomotor response (OMR) is a reflex used to assess visual function. The PhenoSys qOMR (quantitative optomotor response) is a unique system that automatically measures the OMR with minimal experimenter effort. It uses a virtual stimulation cylinder that continuously aligns with the animal´s head position. Based on real-time head tracking, quantitative OMR measurements run fully automatically and objectively. This is a PhenoSys Collaboration product brought to market together with its developer, Dr. Friedrich Kretschmer.
Check out this video to see how it is operated.
2. Characterisation or preclinical testing in relevant disease models, for example:
3. Examination of axonal regeneration.
The PhenoSys qOMR is a PhenoSys Collaboration product. These products are brought to market together with the scientists who developed them.
qOMR is a joint product of Dr. Friedrich Kretschmer and PhenoSys.
qOMR is based on his publications:
Principle of the experiment with a mouse on top of the platform. The stimulus is normally invisible to the IR camera.
Video-based real-time tracking of head movement.
Software omrStudio: stimulus design.
Software omrStudio: running experiment.
Actual measurement data (single frame) and recorded video with superimposed tracking results:
qOMR video with visible stimulus.
The visibility of the stimulus is enhanced compared to the normal qOMR for better clarity.
