The aim is analysis of EEG-rhythms spectral capacity during biofeedback session by heart rhythm variability (HRV) parameters in dependence from serum serotonin level. The were surveyed 53 girls 15—17 years of Arkhangelsk. The girls with a deficit of serotonin to achieve positive results biofeedback-training is accompanied by desynchronization EEG components, which results in reduced spectral power of EEG α-, β- and θ-activity. At the level of serotonin in the blood serum in the normal range for girls is an increase in spectral power of α-activity in thethe anterior parts of of the brain.
