Zebrafish have traditionally been used as effective genetic and developmental models in biomedical research. Recently, the scope and utility of zebrafish in biomedical research has been further expanded with the implementation of new genetic techniques aimed at developing translational models of human pathogenesis. Additionally, screens measuring specific neurobehavioral and developmental phenotypes have proven to be very robust. This chapter further discusses the utility of zebrafish in biomedical research and highlights some of the genetic techniques used in the creation of transgenic and mutant strains. Behavioral phenotypes of genetically altered zebrafish are also discussed with respect to both their robust stress responses and similarity to human disorders. Specific emphasis is placed on human brain pathogenesis and neurodevelopmental abnormalities, especially as they relate to stress and anxiety spectrum disorders.
