Comparison of coherence and phase synchronization of the human sleep electroencephalogram

Popis výsledku v původním jazyce

Objective: Potential differences between coherence and phase synchronization analyses of human sleep electroencephalogram (EEG) are assessed and occurrences of phase vs. complete synchronization between EEG signals from different locations during different sleep stages are investigated. Methods: Linear spectral coherence, mean phase coherence (MPC) z-score and Pearson?s correlation coefficient of analytic amplitudes were evaluated for different spectral bands of whole-night EEG recordings from 25 healthy subjects. Results: Coherence and MPC z-score demonstrated practically the same statistical differences between vigilance stages, confirming the findings of previous coherence-based studies. MPC z-score and amplitude correlations were most correlated (>0.5) between homologous interhemispheric positions and least correlated between nonhomologous interhemispheric positions and between fronto-occipital positions. Conclusions: Coherence and phase synchronization provided essentially the sam
