The electroencephalography (EEG) method has been used to study peculiarities of the bioelectric activity of brain in Khakassia native people (Russian and Khakas of any sex) representing different types of temperament. The Rusalov questionnaire was used. The background EEG was recorded, as well as the EEG with the application of the standard set of trigger samples. The data obtained have shown no general differences between Russians and Khakases in the bioelectric activity of brain. However, the comparison of EEG data with the data of psychological testing revealed some peculiarities. In Khakas men in the left cerebral hemisphere and in women in the both hemispheres, the intensification of the amplitude in the α-region is observed in groups with high-emotional middle-active and low-emotional middle-active types of temperament. This confirms the assumption on the existence of genetically determined peculiarities of the nervous system characteristic of Khakases.
