Electroencephalographic Study of Prefrontal Cortex Among Youth Athletes Has Given Their Temperament

Abstract

The problem of studies is the determination of hypothetical predictors for personality traits among five generalized EEG rhythms in the prefrontal cortex of youth soccer players. The goal of study was to explore the relationship between the oscillations of EEG rhythms in the prefrontal cortex and the personality traits of undergraduates of Sports University . The EEG was recorded using a wireless system with dry non-contact frontal sensor electrodes. The power spectrum was analyzed in five frequency bands (1-50 Hz). Personality traits determination was performed using Eysenck's personality questionnaire. A pair linear regression model, the Spearman's rank correlation and Kruskal - Wallis tests were used for analysis. The research revealed dominance of the extraversive peculiarity of the nervous system over introversive, which is likely due to preference for students, as groups as team interactions rather than individual behavioral strategies. Additionally, the findings of the study determined two slow EEG rhythms as predictors of personality traits among extraverts. It was found that delta rhythm is a correlate of extraversion, and theta rhythm is neuroticism with inversely proportional relationships. These EEG patterns of the prefrontal cortex are related to the features of behavior of youth soccer players of the extraversive type, which is caused by their temperament.
