title: [Autism spectrum disorder. Contemporary experimental researches review].
abstract: Autism, like schizophrenia, are heterogeneous diseases, which are directed by both genetic factors and external influences in the early stages of development. Knowledge about the similarities and differences of these disorders can help early diagnosis and treatment. Patients with autism have specific cognitive difficulties in social relations. They are characterized by impairment of social interaction, communication and behavioral flexibility. The severity of the delay the development of autistic children, clinical and psychological indicators is correlated with an increase in the high frequency of spontaneous EEG activity. Cognitive task in autistic children, unlike normal persons, does not lead to a significant restructuring of high-frequency EEG activity, which may be a violation of the reaction mechanism to external stimuli and behavioral disorders. Abnormality in high-frequency components of EEG reactivity on cognitive task, the perception of human faces and visual illusions as well as the inadequate system of mirror neurons, can be considered common mechanisms underlying disorders of autism and schizophrenia. These general mechanisms may be considered as related to violation of the inhibition-exitation balance, controlled via GABA-transmission and NMDA-receptors. A multidimensional study of patterns of disontogenesis in autism, in addition to detailing the clinical picture of disease and rehabilitation activities, allows us to clear the fundamental understanding of the brain.
