Comprehensive characterization of motor and coordination functions in three adolescent wild-type mouse strains

Abstract Neuropsychiatric disorders are often associated with motor and coordination abnormalities that have important implications on the etiology, pathophysiology, and management of these disorders. Although the onset of many neuropsychiatric disorders including autism spectrum disorder, schizophr...
