| description | The purpose of the work, the results of which are presented within the the article, was to study changes in the nonlinear EEG parameters represented by sample entropy, correlation dimension, fractal dimension, Lempel-Ziv complexity while the operator is irradiated with electromagnetic noise. Apart from the above nonlinear parameters, we studied the change in the power spectral density of delta-, theta-, alpha-, and beta-rhythms. A change in the spectral power density of beta- and theta-rhythms, fractal dimension, and sample entropy during irradiation was associated with a change in the above parameters during depression. A change in the spectral power density of delta-, theta-, alpha-, and beta-rhythms, the correlation dimension, and Lempel-Ziv complexity during irradiation was associated with a change in the above parameters in stress. A change in the spectral power density of the theta rhythm, sample entropy and Lempel-Ziv complexity during irradiation was associated with a change in the above parameters during mental fatigue. The power of the electromagnetic noise generator was 30 mW, the spectral range was 5 GHz, and the generator itself was a generator of electromagnetic noise radiation on transistors. The mathematical description of the calculation of nonlinear parameters represented by sample entropy, correlation dimension, fractal dimension and Lempel-Ziv complexity was studied. The registration of electroencephalograms was carried out according to the “10/20” scheme using the MBN electroencephalograph. The results of the work showed the presence of a depressive and stressful state, as well as the absence of mental fatigue when exposed to electromagnetic noise radiation, if we are guided by the change in sample entropy, correlation dimension, fractal |
