Coherence analysis can detect the coordination of EEG rhythms between brain areas. Is a method developed on the base of classic coherence analysis and signals joint time-frequency representations in recent years. It was used to extract transient characteristics of interactions among brain areas. Describes the temporal, spatial and frequency relationships of brain activities. In this analysis discuss the frequency-varying coherence of EEG (Electroencephalogram) to examine the coordination mechanism of the brain. The power spectral density…
