Behavioral analyses in mouse models of autism spectrum disorders.

Autism spectrum disorder is a group of genetically-related developmental disorders of the nervous system. Patients mainly present with core symptoms such as social behavior defects, repetitive stereotyped behaviors, and learning and memory disorders. The mouse models are critical for the studies of the pathogenic mechanisms and potential therapeutic strategies of autism spectrum disorder. The assessments of mouse behaviors provide understandings of the effects of different genetic manipulations as well as pathogenic mechanisms of these diseases. This article describes various mouse behavioral assays corresponding to the core symptoms of ASD patients and provides a detailed description of protocols, cautions, and data analysis for those assays, thereby helping researchers to establish their own experimental designs. In addition, behavioral phenotypes of currently known ASD mouse models are summarized to provide a reference for researchers in the field.
