Description

The optomotor response (OMR) is a reflex used to assess visual function. The PhenoSys qOMR (quantitative optomotor response) is a unique system that objectively measures 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. This is a PhenoSys Collaboration product brought to market together with its developer, Dr. Friedrich Kretschmer. 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 for automated head tracking independent of coat color Adjustable IR-illumination Anti-reflective (and protective) shields for the screens Filter set for scotopic measurements 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 optomotor response. This analysis is fully automated. Batch run option with multiple stimulation protocols.
