WebJan 1, 2012 · The assays described below rely on optomotor responses, direction-selective changes in head or body movement. The optomotor response is usually thought of as a stabilizing reflex, as flies will attempt to turn their heads or bodies to minimize visual slip when presented with a rotating grating ( 1 , 2 ).

The optomotor response is frequently used as a behavioral assay. In zebrafish, the optomotor response is frequently used as a metric of visual performance as it can be reliably evoked from 7 days post fertilization throughout adulthood. The contrast and wavelength (color) of the stripes can be manipulated to assess the specific properties of their visual system, such as testing the contribution of color to motion detection. In flies, the optomotor response is used to understand … WebDec 12, 2024 · Optomotor response measurements After collection, zebrafish embryos were randomly assigned to one of five exposure regimes (Table 1 ).
