    Author: Huang YB, Zou SQ, Yin W, Wang K, Wang H, Hu B.
    Journal: Yi Chuan; 2012 Sep; 34(9):1193-201. PubMed ID: 23017461.
    Abstract:
    As a means of visual function testing and visual related mutants screening, the optokinetic response (OKR) and the optomotor response (OMR) behaviour tests are simple and effective tools for visual functional testing, which have been widely used in studying zebrafish larvae. However, adult zebrafish OKR analysis method is rarely reported. In this study, the methods of inducing adult zebrafish OKR behaviour, as well as tracking the movement of eyes using Pattern Match approaches, are presented. The quantitative measurement of the adult zebrafish OKR behaviour was successfully established. Using these methods, the binocular vision area was found to make a certain contribution to OKR behaviour. Moreover, the monocular vision of adult zebrafish showed a certain degree of directional sensitivity to moving gratings. Such approaches can also be applied to the zebrafish larvae OKR. The abnormal OKR behaviour phenomenon of period1b mutant larvae fish was detected.
