Abstract
The zebrafish is increasingly employed in behavioral neuroscience as a translationally relevant model organism for human central nervous system disorders. One of the most prevalent CNS disorders representing an unmet medical need is the disorder cluster defined under the umbrella term anxiety disorders. Zebrafish have been shown to respond to a variety of anxiety and fear inducing stimuli and have been suggested for modeling human anxiety. Here, we describe a simple method with which we intend to induce fear/anxiety responses in this species. The method allows us to deliver a visual and lateral line stimulus (vibration or "tapping") to the fish with the use of a moving object, a ball colliding with the side glass of the experimental tank. We describe the hardware construction of the apparatus and the procedure of the behavioral paradigm. We also present data on how zebrafish respond to the tapping. Our results demonstrate that the method induces significant fear/anxiety responses. We argue that the simplicity of the method and the efficiency of the paradigm should make it popular among those who plan to use zebrafish as a tool in anxiety research.
