[Neurophysiological studies in autism spectrum disorders--comparison with those in schizophrenia].

There have been reports that autism spectrum disorders (ASD) share common symptoms with schizophrenia. Several imaging studies showed the overlap of the impaired brain circuit in ASD and schizophrenia. Accordingly, differential diagnoses between adult ASD and schizophrenia without positive symptoms are sometimes difficult. We examined whether they show common results in functional MRI studies involving viewing photos of different facial...
