OptoMotor Response (OMR) is a reflex used to assess visual function
OptoMotor Response (OMR) is a reflex used to assess visual function. To evoke OMR, a mouse watches a striped pattern rotating within a cylinder. Stimulus-correlated head movements are quantified to determine visual thresholds.
The PhenoSys qOMR (quantitative OMR) is a unique system that automatically measures OMR with minimal experimenter effort.
It uses a virtual stimulation sphere 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 that is brought to market together with its developer, Dr. Friedrich Kretschmer.
Hardware features
Calibrated 4-screen environment for presenting the virtual stimulation cylinder
Elevated central platform for placing the unrestrained animal
Top and bottom mirrors to create the illusion of infinite depth for optimized stimulation
IR camera with adjustable IR illumination for automated head tracking
IR illumination for automated head tracking.
Software features
Video-based real-time tracking of head movement is used for both:
1. Continuous automated position adjustment of the virtual cylinder to the animal´s head position.
2. Evaluation of head movement synchronous to the stimulation for a quantitative measure of the OMR. This analysis is fully automated.
Batch run option with multiple stimulation protocols.
These capabilities will help your laboratory achieve outstanding results
The measurement and analysis are automated
The experiment is unbiased, time-saving, and cost-effective.
No training required
Because the stimulus doesn't have to be manually positioned, there is no need for a trained experimenter.
