title: [A correlational analysis of the EEG rhythms and functional hemispheric asymmetry in children with the hyperdynamic syndrome].
abstract: Thirty-three mentally normal children aged 4.5 to 11 years with hyperdynamia were examined for their EEG. In the profile of functional asymmetry (PFA) detected by the leading hand and eye, a considerable portion, as compared to normals, was made up of ambidextrous children with no left-handers. Depending on the pattern of biopotentials, two types were distinguished in the EEG. Each of the type covered children with different PFA. The cross-correlations inside and interhemispheric relations were different in children with different PFA and depended on the EEG type. The children with hyperdynamia were shown to have the weakening of the intrahemispheric correlations by the alpha rhythm together with their potentiation according to the beta rhythms, a decrease of positive interhemispheric asymmetries, and a great number of negative asymmetries.
