Background. Every day, every person is affected by a whole range of factors that are emotional and stressful in nature, which can lead to the appearance of oncological or cardiovascular diseases. It is known that up to 20 % of the world's population is prone to anxiety and depression, regardless of race, region and wealth level. The aim of the work is to develop and study an original algorithm for the complex processing and analysis of electroencephalographic signals in people under conditions of emotional arousal. Materials and methods. For the research, a sample of 30 subjects, aged from 23 to 28 years, was formed, who gave their voluntary consent to the experiment in accordance with the protocol of the clinical trial. Measurement of electroencephalographic signals parameters was carried out in a calm state, in a natural load and six modes of audiovisual stimulation (sleep, learn, energ, create, fun, special). To compare the obtained results, numerical methods of analysis were carried out: amplitude, spectral and correlation. Results and conclusions. As a result of the research, it was found that in the audiovisual stimulation mode with open eyes and energ, the process of excitation of the cerebral hemispheres is recorded, which indicates a pronounced picture of the emotional state. In the sleep and fun modes, stabilization of emotional stress is recorded. |
