Modeling mouse anxiety and sensorimotor integration: Neurobehavioral phenotypes in the suok test

Abstract

Animal behavioral tests are useful tools for modeling complex human brain disorders. The Suok test (ST) is a relatively new behavioral paradigm that simultaneously examines anxiety and neurological/vestibular phenotypes in rodents. The novelty and instability of the ST apparatus induces anxiety-related behavior in mice, whereas the elevation of the horizontal rod allows for the assessment of motor and neurological phenotypes. This chapter discusses the utility of the ST in detecting mouse anxiety, habituation, exploration, motorisensory deficits, and the interplay between these domains. With a growing number of laboratories using this model, a detailed protocol for the ST behavioral analysis (with a focus on video-tracking tools and novel applications) is also provided. © 2011 Springer Science+Business Media, LLC.
