Numerical values of some cluster locations shown in Fig. 10. Each coordinate Inline graphic and Inline graphic specifies the centroid of mass of the corresponding significant cluster. The time Inline graphic denotes the time after stimulus onset. Here, the directivity is expressed by the sign of the delay time: Inline graphic describes a connectivity from frontal to temporal and Inline graphic from temporal to frontal. The conditions Pre, Post, Neutral, Negative and the corresponding contrasts are arranged in the same way as the patterns of connectivity displayed in Fig. 10.
