[The frequency characteristics of EEG spectra in emotions]

The study is devoted to analysis of EEG frequency spectral characteristics during mental reproduction by subjects of joy, anger, fear, and sorrow. Significant differences between the emotional states are revealed in the points C4, T4, F3, O1 by the mean alpha-frequency (p < 0.05). Two opposite tendencies are revealed, i.e., joy and anger are mainly characterized by an increase of the alpha peak frequency in respect to the background values, whereas its decrease is seen in fear and sorrow.
