[Frequency-decrement electroencephalogram analysis by model of rhythmic processes of bioelectrical activity of the...

The results obtained earlier showed that the electroencephalogram is represented as convolution of harmonic functions having negative decrements with discrete evenly discontinuous white Gaussian noise. The method of EEG decrements calculation has been proposed and tested on model processes with set-up parameters and on real rat encephalograms. Studies of decrement characteristics along with amplitude-frequency characteristics of encephalograms in different functional states of animals will extend the possibilities of the mathematical processing of brain signals.
