Frequency characteristics of EEG spectra in the emotions

The present investigation was devoted to a spectral analysis of EEG frequency constituents during the ideational reproduction of the emotions of joy, anger, fear, and sorrow in man. Significant differences (p<0.05) in the emotional states were detected with respect to average alpha rhythm frequency for the C4, T4, F3, and O1 leads. The presence of two opposite tendencies in the character of the shifts in the peak alpha frequency by comparison with the baseline was demonstrated: an increase for the emotions of joy and anger and a decrease for sorrow and fear.
