BIOELECTRIC ACTIVITY FEATURES OF THE BRAIN IN FINAL-YEAR FEMALE STUDENTS DEPENDING ON THEIR ANXIETY LEVEL

Keywords: Electroencephalography, anxiety, female students, alpha rhythm, theta rhythm, coherence

Abstract

Aim. This article deals with the assessment of the bioelectric activity of the brain in finalyear female students depending on their anxiety level. Materials and methods. The study involved 32 final-year female students in the intersession period and 24 female students in the session period. The amplitude, frequency and EEG rhythm index were established using EEG spectral analysis. We also used the coherent analysis of EEG to reveal connections between different areas of the brain. Results. Higher situational anxiety is characterized by the increased coherence and decreased amplitude of alpha and theta rhythm. The analysis of EEG frequencies demonstrated the differences between the intersession and session periods only for a theta range. Theta activity dominated in female students with lower personal anxiety. In the session period in comparison with the intersession period we registered the highest values of theta rhythm in the frontal lobes in female students with high personal anxiety. Increased coherence was registered mainly in fronto-central and centro-temporal areas of the right hemisphere. In participants with low situational anxiety we established decreased coherence in the left temporal area for alpha rhythm and in the right fronto-central and left fronto-temporal areas for beta rhythm. In the intersession period in girls with low situational anxiety we registered decreased coherence in the left parieto-occipital, left fronto-parietal and right fronto-temporal areas for a beta range and in the right fronto-parietal area for theta rhythm. The most significant theta activity was registered in students with moderate personal anxiety in upper-frontal, central, left parietal, left occipital and right lower frontal areas. Conclusions. For the majority of female students low situational and high personal anxiety were typical for intersession and session periods. Girls with low situational anxiety were characterized by an increase in the amplitude of alpha rhythm during the intersession period and by an increase in theta rhythm in the session period.
