[Electroencephalographic correlates of individual features of the mental efficiency of adolescents]. 1985

D A Farber, and V I Kirpichev

Evident correlations of spatial-temporal organization of the electrical brain activity with individual features of the mental working capacity were revealed in juveniles by the methods of analysis of spectra power density and of coherence function of rhythmic EEG components. EEG in juveniles with a low working mental capacity is characterized by hypersynchroneity, monofrequency, low reactivity of alpha-rhythm and high level of generalized spatial synchronization. Juveniles with high level of mental working capacity are characterized by regional specificity of the main EEG rhythm, the presence of the local dynamic foci of interconnected activity. It is suggested that the correlation of mechanisms of controlled local and non-specific generalized cortical activity is one of the main factors, determining the individual specificity of mental ability.
