[The functional brain characteristics of people working within the 30-kilometer area of the Chernobyl Atomic Electric Power Station from the viewpoint of age-related changes].
Features of the brain functional status were evaluated by mapping of spontaneous and evoked electrical activity of the brain as were the processes of aging of the nervous system, in 402 individuals who have been working within 30-km of the Chernobyl Nuclear Power Station (CNPS), 100 participants in combat in Afghanistan and 20 healthy residents from regions with pollution-free ecological environment. In subjects who had been at the CNPS distinguishing features were noted of the electrical activity of the brain at rest and in the process of processing of sensory information, which were manifested by alterations in interhemispheric and cortico-subcortical relations and were not associated with age but were dependent on a radiation dose. At the same time CNS functional age corresponds to an older age in the irradiated subjects aged under 35 and to a younger one in those over 35 years of age.
