| Popis: | Zebrafish are a popular vertebrate animal model for biomedical research including investigations of the auditory system. Responses to acoustic stimulation have been a challenge to carefully measure in zebrafish. Here, the authors have developed a procedure for measuring hearing sensitivity in adult zebrafish using an appetitive automated Go/No Go task. In this task, a trial is initiated when a fish passes through an observing gate. In a sound trial, the fish is reinforced by an automated food delivery system when it enters the reinforcement compartment. If the fish enters the reinforcement compartment during a no-sound trial, a timeout is implemented. Zebrafish successfully learned this task in a median of about ten days of daily training. Zebrafish were most sensitive at a frequency of 800 Hz, which corresponds well with sensitivity reported from physiological methods. As far as the authors know, the present study is the first to provide hearing thresholds for zebrafish using a conventional combination of operant conditioning and psychophysical procedures. This could open the door to other kinds of tests using acoustic stimuli as are commonly conducted in many other laboratory animals. |
