The study of changes in EEG activity in spatial tasks in disabilities children in primary school

In this work presents a study of the features of alpha rhythm formation before and after cognitive load in children aged 9-10 years. Experimental studies were conducted for two groups of children of 5 people (a group with visual disabilities up to 25%, a group with almost normal vision from 80%). In General, a decrease in the alpha-rhythm power was demonstrated for the group of disabilities children in comparison with the group of practically healthy subjects. Spatial maps of the alpha rhythm distribution are presented, showing the features of localization of this rhythm during passive wakefulness and solving cognitive tasks.
