Phenotyping of zebrafish homebase behaviors in novelty-based tests

Abstract

Various novelty-based assays used to quantify zebrafish (Danio rerio) behavior show a striking similarity to behavioral responses in rodents. Exposed to the open field test, zebrafish establish overt homebases demonstrating clear preference for a particular area of the tank. This behavior aims to establish a "safe zone" that zebrafish can familiarize themselves with and feel secure in, and is similar to homebase behaviors of various laboratory rodent species. Here we outline a simple protocol for homebase phenotyping in zebrafish. © 2011 Springer Science+Business Media, LLC.
