Analysis of brain functional status in students with high and low rates of mental activity

The purpose of this paper is to analyze the brain functional status in students with high and low rates of mental activity. Materials and Methods. The study enrolled 183 volunteers, namely young women aged 19-22. At the baseline, the EEG was recorded using the Electroencephalograph-analyzer EEGA-21/26 “Encephalan-131-03”; then the students underwent a proof-reading test. Results. During the study, we identified groups of subjects with high and low rates of mental activity on the basis of factor analysis. In subjects who demonstrated a vast amount of mental activity, the initial state of the nervous system was characterized by the dependence of the cerebral cortex activity level on the ascending pathways on the thalamus and hippocampus cortex and the balance between excitation and inhibition in the cerebral cortex. In subjects with a high rate of mental activity the initial state of the nervous system was characterized by the link between the cerebral cortex activity level and the coordinated influence of the hippocampus and the thalamus on the cerebral cortex and by the balance excitation and inhibition in the cerebral cortex...
