| Abstract: | A quantitative study was conducted on stress reaction in rat induced by 35 GHz millimeter wave. Long-range correlations analysis of the rat electroencephalogram (EEG) was investigated. The scaling exponents α1 and α2 were calculated by detrended fluctuation analysis (DFA) method. The exponent α1 shows that the high frequency EEG component is characterized by Brownian noise before irradiated by 35 GHz millimeter wave while it has long-range correlations during irradiation. The exponent α2 shows that the low frequency EEG component has long-range correlations before irradiation while it is characterized by Brownian noise during irradiation. Introducing stress parameter k(k=α2/α1), the average change rate of k was used to evaluate the intensity of stress in rat evoked by 35 GHz millimet |
