Changes of the eeg oscillations in the temporal lobe of the cerebral cortex under the effect of examination process in students with choleric temperament

Abstract

To identify age-related changes in the amplitudes of delta, theta, alpha and beta waves in the temporal lobes of the cerebral cortex during emotional  stress caused by examination process in choleric students. The research involved 23 male students with choleric temperament aged 17 and 21. EEG  recording of the right and left temporal lobes was carried out for 10-12 minutes on ordinary days (OD), as well as before (BE) and after exam (AE). The  type of temperament of students was determined according to test of Eysenck before starting the experiment. The personal and situational level of  anxiety was determined according to Spielberger in 3 states: on ordinary days (OD), before the exam (BE) and after the exam (AE). It was established that  differences in the electrical activity of the brain of 1st year and 5th year choleric students were observed in all stages (OD, BE, AE). In 17-year-old choleric  students, the amplitude of the EEG delta, theta and alpha waves on both sides of the temporal lobe changed in waves under the influence of emotional  tension in the 1st semester of the BE and AE periods, while the amplitude of the EEG beta waves in the AE periods sharply decreased, which differed from  the indicators in the 5th year. Data on the oscillations of EEG waves in the temporal lobe of the cerebral cortex of students can be used for an  objective method of diagnosing students' psycho-emotional stress and determining the ways of self-regulation of their condition.
