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.

WebThe OFF SACs were relatively preserved in mice exhibiting continued fear responses, whereas they were ablated in mice lacking fear response to looming stimulation. These results indicate that OFF SACs and the direction-selective pathway in the retina play a role in looming-induced fear behaviors. Significance Statement In response to a suddenly ... WebOct 15, 2024 · The Optomotor Response Is Preferentially Elicited after a Light-Dark Transition To determine the spatiotemporal luminance features that induce forward-swimming behavior, we presented head-restrained larval zebrafish with a forward-moving whole-field visual stimulus consisting of black and white bars from below (Figure 2 A).
