Abstract

Zebrafish (Danio rerio) are emerging as a promising model species in neuroscience research. Many traditional rodent behavioral paradigms may be adapted for zebrafish testing. Exposing zebrafish to three different " open field" tanks for 30min, we showed that fish display robust homebase behavior, in which one area of the tank is chosen as a preferred point of reference during the test, which the fish frequently return to and spend a longer duration in. This phenotype strikingly resembles rodent homebase behavior, confirming that both species use homebases as " reference points" for their exploration. Our study introduces a simple method for zebrafish homebase phenotyping, and further supports the utility of these fish in neurobehavioral and cognitive research.
