Optomotor assay
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 … WebJun 26, 2024 · Optomotor response/reflex (OMR) assays are emerging as a powerful and versatile tool for phenotypic study and new drug discovery for eye and brain disorders.
