Using the optokinetic response to study visual function of zebrafish
Optokinetic response has been widely used to assess the visual functions of larval zebrafish. Nevertheless, the standard protocol for larval fish is not yet readily applicable in adults1-5. Here, we introduce how to measure the OKR of adult zebrafish using a new protocol which is established in our lab.

VisioTracker, an Innovative Automated Approach to Oculomotor Analysis
1Institute of Molecular Life Sciences, University of Zurich, 2TSE Systems GmbH
The VisioTracker is an automated system for the quantitative analysis of visual performance of larval and small adult fish based on the recording of eye movements. It features full control over visual stimulus properties and real-time analysis, enabling high-throughput research in fields such as visual system development and function, pharmacology, neural circuit studies and sensorimotor integration.

Video-oculography in Mice
1Department of Neuroscience, Erasmus MC, Rotterdam, The Netherlands, 2Department of Neuroscience, Royal Dutch Academy of Arts & Sciences (KNAW)
Video-oculography is a very quantitative method to investigate ocular motor performance as well as motor learning. Here, we describe how to measure video-oculography in mice. Applying this technique on normal, pharmacologically-treated or genetically modified mice is a powerful research tool to explore the underlying physiology of motor behaviors.

A Behavioral Assay to Measure Responsiveness of Zebrafish to Changes in Light Intensities
Department of Molecular and Cell Biology, Harvard
We developed the Visual-Motor Response to quantitate the motor output of larval zebrafish in response to light increments and decrements. We also examined zebrafish vision mutants, including the no optokinetic response (nrc) mutants, which were thought to be completely blind when tested by another vision assay, the optokinetic reflex.
