[Spatial relationships of electrical activity during reproduction of verbal signals in children].
The study of intercentral correlations of the brain biopotentials in five-to six year old children revealed considerable differences in the spatial distribution of interrelations of the neocortex projection and associative zones during reproduction of familiar and unfamiliar words. Reproduction of familiar words was accompanied by the greatest enhancement of interrelations of associative structures (infraparietal, frontal areas and Broca speech centre) with projection zones of the motor and acoustic analysers in the left hemisphere, while reproduction of unfamiliar words was attented with closer connections of the projection motor zone with the temporal and the anterior associative (frontal and speech) zones in the right hemisphere. The facts obtained testify to the existence of the interhemispheric asymmetry and to the different involvement of the neocortex projection and associative zones in the organization of motor speech in children.
