    Abstract:
    Frequency characteristics of EEG-reaction have been analysed in children of 3-10 years in the process of realization of the orienting reflex to sound stimuli. An enhancement of theta- and alpha-oscillations has been found in such conditions which becomes less pronounced to 9-10 years. In the last age group, the reaction of blockade of the basic rhythm of the background EEG (alpha-oscillations of 10 Hz) is formed, combined with local enhancement of other rhythmic components of this frequency range. Functional significance of different forms of EEG activation reaction has been determined. The question is discussed of functional heterogeneity of rhythmic components of the alpha-range and their differential involvement in the reaction reflecting complex mechanisms of cortical activation.
