Simulated Research on Stochastic Resonance Phenomenon of EEG Dynamics Model
Xue Lingyun · Jisuanji fangzhen · 2008
As to cerebrum behaviour studies, the research on stochastic resonance phenomenon in electroencephalogram (EEG) has shown its important role, both on theory or in practice. By utilizing contrast means of signal-to-noise ratio, cross-correlation coefficient and mutual information rate, in order to simulate ability of cerebrum system in signal detection, stochastic resonance in EEG dynamics model was studied. Results indicate that, in EEG dynamics model, there exists not only periodic stochastic resonance phenomenon, but also aperiodic stochastic resonance phenomenon. Thus, this study gives a new evidence about the view that stochastic resonance phenomenon exists in cerebrum system.
