Optomotor response assay
WebJul 18, 2024 · Optomotor response is increasingly used in preclinical research for evaluating the visual function in rodents. However, the most suitable measuring protocol for specific scientific questions is not always established. We aimed to determine the optimal parameters for visual function analysis in experimental autoimmune encephalomyelitis … WebMay 15, 2024 · A circular optomotor response assay for testing vision As in Suriyampola et al. (2024), we tested a single, randomly-selected fish from each group ( N = 58) in a circular optomotor response (OMR) assay to compare the response of adult zebrafish from each treatment to visual stimuli.

WebMacGinitie 1965). The optomotor response is absent if the drum is still, or if the animal cannot detect visual features on which to fixate. Comparing responses to a series of incremental stimuli can therefore be used to determine detection limits. The optomotor response is innate and present in diverse taxa, including mammals http://lab.brembs.net/wp/wp-content/uploads/2024/07/Lab-internship-report-Optomotor-response-screening-Simon-Benmaamar-2.pdf
WebTo solve this problem, we have developed an operant conditioning assay that allows determination of TCS functions in behaving mice. Indeed, the temporal resolution of the optomotor response is limited to ~12 Hz, while visual responses measured with our new operant approach extend to ~50 Hz.

WebJun 30, 2024 · By 5 days post-fertilization, zebrafish have quantifiable behavioral responses to visual stimuli. Their small size, many progeny, and external fertilization allows for rapid screening for vision defects. We have adapted the OptoMotor Response to assay visual impairment in zebrafish models of cataracts and microphthalmia.
