WebOptomotor Response The optomotor response (OMR) is a reflex often used to assess visual abilities. To evoke OMR a rotating cylinder with a striped pattern is presented to an animal on an elevated platform. The resulting head movements are evaluated in relation to the presented stimulus to determine thresholds of visual recognition. http://lab.brembs.net/wp/wp-content/uploads/2024/07/Lab-internship-report-Optomotor-response-screening-Simon-Benmaamar-2.pdf takeoff autopsy pics
