UCLA is a recognized leader in the field of genomics as well as disease progression and treatment development. The Behavioral Testing Core facility provides a much needed service and enhances further the standing of the UCLA research community in behavioral genetics. Our facility brings researchers together in a collaborative effort to link genes, disorders, and treatments with behavior. The facility is available to all UCLA researchers, as well as outsider researchers, interested in the determination of behavioral phenotypes in different mouse and rat strains and the effects that various treatment options have on these phenotypic characteristics. The Behavioral Testing Core was established with the assistance of the Howard Hughes Medical Institute and is supported by the UCLA Bioscience Core Funding Initiative. Fees paid by individual users support the daily operations of our facilities.
