Electrophysiological Features of Brain Electric Activity in Individuals with Different Social Behavior

Abstract

The article is devoted to the study of differences in the brain’s work of people with different social orientation by recording the electrical activity of the brain cortex. 120 (aged 21±4 years) individuals took part in the study. As a result of psychological testing (based on Leary-s test) all subjects were divided into two groups – altruistic and egoistic. Registration of electrical activity was carried out during “Stag Hunt Game” and during a specially developed model of social behavior “Mini Basketball Game”. As a result, synchronization processes are better expressed in the individuals with egoistic sociotype, and desynchronization processes are better expressed in the individuals with altruistic sociotype in alpha- and betha-range. Sources of activity are represented by the structures of brain cortex frontal areas in altruistically directed individuals and by the structures of the brain cortex insula area in egoistic individuals.
