摘要：

A method of modified coherence analysis was applied to the interpretation of EEG differences between the frontal and occipital cortex. This paper discusses a bidirectional communication model for the frontal and occipital cortex. Directed coherence method was used to analyze alpha-activities over the scalp. The results show that both in the left and right hemisphere, slow waves in the alpha-frequency band had high correlation in the frontal-occipital direction, and fast waves had high correlation in the occipital-frontal direction. It may suggest that the structure of information transmission is different for fast and slow waves of alpha-rhythm.
