[The spatial synchronization of cortical bioelectrical activity in different degrees of severity of alcohol...

Stage-II alcoholics were examined 1-2 weeks after drinking periods, as were alcoholics during remissions lasting for 0.5 to 6 years. EEG was recorded by 10 symmetrical leads: prefrontal, central, motor, sincipital, and temporal. Analysis of EEG correlations revealed reliable differences between the two groups in the total level of synchronism of cortical biopotentials, in activities of different regions, and in time course of relationships of various areas during hyperventilation and without it. The data may be used as objective criteria in assessment of the degree of a pathologic process in the CNS and for differentiating the patients by this sign for further differentiated therapy.
