Popis: The character of interhemispheric distribution of frequency-amplitude parameters of EEG as a function of the strength of emotional experience, the intensity of drive, and the expected probability of its satisfaction were determined in human test subjects. The emotional state was aroused by an imaginary reproduction of emotionally colored events. The modified test by D. Price and co-authors was used where the subjects estimated the intensity of drive (the degree of undesirability of imaginary event) and the expected probability of its occurrence by the length of line segment. In this study, the simulation of anger was used. The highest correlation coefficients were observed between the expectation and power in the α-EEG-range in the left frontal region. The strength of emotional experience negatively correlated with the α-, θ-, and Δ-ranges. Statistically significant correlation was revealed between the intensity of drive and power of Δ- and θ-waves. The power of β-rhythm correlated with the strength of emotion as well as with the expectation and drive indices.
