Time evaluation of the correlation technique is applied for every available contact pair to determine dependencies between EEG channels. This produces a large amount of results that are not easy to interpret. Here we introduce a procedure for complex and comprehensive result imaging which helps us focus on significant parts of the results. Changes of power are examined along with correlation changes. Results are demonstrated for one subject. Five channels were selected from the hippocampus for detailed analysis. How the changes of correlation are connected to changes of power is shown in addition to the coupling between channels.
