Figure 3. Directed Information (DI) and Directed Feature Information (DFI).

Figure 3

Having identified in Fig. 2 What features the brain of Observer 1 processes for perceptual decisions (framed in blue and red in Fig. 2 and here), with DFI we illustrate coding and transfer of these features between right (node A) and left (node B) occipito-temporal regions and inferior parietal region (node C). MI. Color-coded Mutual Information times courses for each feature (single-trial left and right nun’s faces values, see corresponding color-coded rasters) and network node (single-trial MEG activity). DI. Directed Information reveals that A and B send MEG signal information to C with a ~120 ms of delay. DFI. Directed Feature Information reveals the transfer that is about each feature, reconstructing two links of an information processing network of three nodes.
