[Characteristics of the mean level of asymmetry of EEG phase durations in children from 3 to 7-years-old].
Electrical activity in three to seven-year old children was investigated by the criterion of correlations between the duration of ascending and descending phases of EEG oscillations--the mean level of asymmetry (MLA) during calm alertness and physiological loads. The existence of a positive and negative MLA and considerable variation boundaries of the parameter are the distinguishing properties of the child's background EEG. The parameters of the summary MLA shift and the dynamics of fluctuations of the successive second asymmetry values made it possible to obtain quantitative and qualitative characteristics of EEG reactions. An increase of the range of the second MLA oscillations is the basic form of reaction in preschool children. The greatest quantiative and qualitative shifts are produced by emotiogenic stimulation.
