Examining Autism Spectrum Disorders by Biomarkers: Example From the Oxytocin and Serotonin Systems

Using neurochemical biomarkers to perform parallel studies in animal and human populations within a developmental context is a plausible approach to probe the root causes of ASD and to identify potential interventions.
