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 WebRomand Raymond is an academic researcher.

The optomotor response is a central feature of a fly's flight control system: flies subject to unplanned apparent self-motion move to minimize the resultant optic flow (retinal movement patterns) and correct involuntary deviations from course. See more In behavioral biology, the optomotor response is an innate, orienting behavior evoked by whole-field visual motion and is common to fish and insects during locomotion, such as swimming, walking and flying. … See more The optomotor response is essential for animals to correct unplanned course perturbations while navigating through their environment, … See more Both behavioral and physiological optomotor responses have distinct tuning curves for the temporal, spatial and contrast structure of moving images. The magnitude and time-course of the optomotor response to optic flow depends on the temporal … See more The optomotor response is frequently used as a behavioral assay. In zebrafish, the optomotor response is frequently used as a metric of See more WebMar 27, 2013 · To test whether the impaired optomotor response depends on CRY function in the compound eyes, we selectively rescued CRY in the eyes with the help of the upstream activating sequences (UAS)-GAL4 system, driving GAL4 under control of the eye-specific glass multiple reporter (gmrGAL4) . gmr-GAL4 is known to disturb the structure of the …
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. WebAug 4, 2024 · Various procedures have been adopted to investigate spectral sensitivity of animals, e.g. absorption spectra of visual pigments, electroretinography, optokinetic response, optomotor response...
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.
