DC-potential of the brain was performed in 97 women 55-74 years old living in the circumpolar region. Study and analysis of the distribution level DC-potential brain mapping was carried out by the measured values of monopolar constant potentials. The resulting distribution characteristics DC-potential compared with the average values for the corresponding normative age period. The features of the distribution of the level of DC-potential in women of circumpolar region at the age of 55-74 years, such as smoothing hemispheric asymmetry and increase total cerebral energy compared with reference values in most parts of the brain.
