Abstract

The paper studies cerebral energy exchange in 150 women aged 60–74 years with high and normal levels of personal anxiety in order to identify peculiarities of the distribution of energy processes in the cerebral cortex as well as their intra- and interhemispheric interactions. Cerebral energy exchange was studied using the 12-channel Neuro-KM hardware and software complex. Women with high level of anxiety showed an increased level of DC potential in the central (Cz and Cs leads), parietal (Pd lead), occipital (Oz lead) and temporal (Td and Ts leads) areas and a decreased level of DC potential in frontal areas (Fpz and Fd leads). It was demonstrated that older women with high level of anxiety have stronger inter- and intrahemispheric (mainly in the right hemisphere) interactions of cerebral energy processes.
