Features of bioelectric brain activity in people with different level of situational anxiety when performing non-verbal tasks

The purpose of the study: to analyze the parameters of the electroencephalogram in individuals with different levels of anxiety when performing non-verbal tasks.Object and methods. The study was conducted on 20 female students, aged 18 to 22 years. All studies were carried out on a voluntary basis, confirmed in writing, in compliance with bioethical standards governing the conduct of observations on humans. The level of situational anxiety was determined using the Spielberg-Khanin test.The spectral power of the electroencephalogram rhythms was recorded using the NVX 36 digital DC EEG neurovisor using a cap with a set of electrodes that were placed on the head of the subjects according to the international 10-20 system. The EEG recording lasted 1-2 minutes before and during the performance of nonverbal tasks. As non-verbal tasks, the subjects were asked to complete the Portsus maze test and the Cattell intellectual test. The results obtained were statistically processed. Differences were considered statistically significant at p function show_eabstract() { $('#eabstract1').hide(); $('#eabstract2').show(); $('#eabstract_expand').hide(); }
