**3. Analysis and Results**

In this section, in order to verify whether the CBTN can characterize the information interaction between two time series, it was first tested on the unidirectional coupled Honen model and its performance was compared with the original CPE method. Next, the complex network constructed by the CBTN was applied to the realistic EEG recordings during either the resting state or the mental arithmetic task in order to evaluate the performance of the proposed method in detecting the changes in the cognitive load.
