  • Title: Interhemispheric interaction in children with autonomic dysfunction of the sinus node.
    Author: Kolesnikova LI, Korolyeva NV, Bugun OV, Kolesnikov SI, Dolgikh VV.
    Journal: Bull Exp Biol Med; 2009 Sep; 148(3):374-7. PubMed ID: 20396692.
    Abstract:
    Electroencephalography was performed in 7-8- and 9-10-year-old pupils. Control group consisted of healthy children; experimental group consisted of children without signs of grade IV and V sinus arrhythmia at the age of 7-8 years, but with grade IV and V sinus arrhythmia at the age of 9-10 years. In primary school-aged children (7-8 years), manifestation of marked sinus arrhythmia is associated with disturbances in age-specific dynamics of interhemispheric interaction and with the formation, at the initial stage, of a rigid integrated system primarily due to functional intrahemispheric connections, the major contribution being made by the posterior associative cortical areas.
