“…In recent years, the number of students experiencing learning difficulties has been steadily growing in all countries, and these are children from all social strata of society [1,2]. Learning problems in different age groups (6-9 years old) were found in 15-40% of children, according to various sources [3,4]. EEG characteristics of preschool age are critical to understanding the causes of school learning difficulties in learning in different age groups, which reflect the significant changes that have occurred in the anatomy and functioning of the child's brain by the beginning of learning because the fine regulation of intercentral relations and interhemispheric asymmetry of the brain marked already in primary school age [5,6,7].…”

The current paper performs a comprehensive assessment of electroencephalogram (EEG) parameters and features of cognitive functions of the brain in children of preschool (6-7) and primary school age (7-8) years with learning difficulties are considered. Spectral and coherent EEG analysis is conducted as well as particularities of gamified orientation in the maze. Spectral analysis of the EEG in children with learning difficulties revealed a speed decrease in the formation of almost all indicators of alpha activity and an increase in the power of slow-wave activity in the EEG, which was more pronounced in the left hemisphere of the brain. EEG coherence analysis revealed early differences in the spatial organization of the coherence function both in EEG rhythms and the cerebral hemispheres. A high level of motor activity in the maze, fragmented perception, unstable attention, low volume of operational memory, and poor optimization of skills in mastering a new space in children with learning difficulties correlated with indicators of age-related neurophysiological immaturity in terms of EEG.
