Optomotor response assay
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. WebMay 4, 2024 · In his paper, Götz stated that the study of the optomotor response requires at least three neural algorithms to be understood: (1) sensing local motion by comparing light intensity changes across adjacent ommatidia, (2) integrating local motion across retina to detect optic flow, and (3) passing this information to appropriate motor programs.

WebMar 17, 2024 · Description: The optokinetic response (OKR) examines the retinal movement (“slip”) due to rapid displacement of images on the retina. In this assay, rapidly moving graphics on an LCD screen or a striped drum are presented in front of a fish and the retinal displacement is recorded videographically. WebThe Optokinetic Response (OKR) Uses Visual Inputs to Stabilize Gaze The OKR also functions to stabilize retinal images during head movements, but uses visual inputs to infer the direction and speed of head motion rather than …
