Bioelectric Brain Activity in Children with Autistic Spectrum Disorders: Population Heterogeneity

Abstract

During the discriminant analysis of the bioelectric brain activity, we found that there is a separate subgroup of children with autistic spectrum disorders that is close to the group of schizophrenia spectrum disorders but does not coincide with it. Differences between the experimental groups indicate the significance of impairments in the left frontal-temporal region, i.e., in the area responsible for speech development. When comparing the group of children with autistic spectrum disorders with other groups, we observed the significance of high-frequency rhythms.
