The effect of 5-HTTLPR on EEG reactions among Yakuts and Russians during the recognition of emotionally colored verbal stimuli

The effect of 5-HTTLPR on an emotional speech perception was studied by means of EEG analysis. Two ethnically different groups (Russians and Yakuts) were compared. No significant ethnic effects were found, but significant interaction of the factors "gender" and "genotype" has been revealed for the aggression containing sentences. 5-HTTLPR modulates the perception of aggression, but its effects are opposite for men and women.
