Speech occupies a special place in formation of cognitive functions. Delay in tempos of speech development can lead to disorders in formation of the highest mental functions. Aim. To study the character of space-time integration of cerebral zones in children with different variants of speech disontogenesis in the course of prospective study by the data of ECG coherent analysis. Materials and methods. 34 children aged 3-11 years were examined by means of quantitative ECG mapping and estimation of mean coherence indices. All children were divided into two groups: group I included children with dysarthria, group II - children with motor dysphasia of development. In each group there were two age subgroups. The first subgroup involved children aged 3-6 years, the second- children aged 7-11 years. Results. It was demonstrated that in process of ontogenesis, different space-time integration models of cerebral zones which determine different clinical pictures of speech dysfunctions were formed. High mean coherence values in preschool children’s left frontotemporal and frontocentral pairs are a positive factor for development of speech in process of ontogenesis. Conclusions. The obtained data give an opportunity to assess the adequacy of therapeutic and correcting measures in age dynamics.
