[The bioelectrical correlates of the personality anxiousness of 2 strong types of higher nervous activity].

Bioelectrical correlates of personality anxiety were studied in subjects with strong types of higher nervous activity. It was shown that the index of general power of the alpha-rhythm inversely depended on the level of anxiety. In sanguine persons the low level of anxiety and incapacity for vivid reproduction of fear were associated with frequent change of asymmetry sign in all EEG recordings. Choleric persons were characterized by the high level of anxiety and the stable dominance of one of the hemispheres manifested in EEG of the frontal and temporal areas.
