Figure 1.
Diagrams showing the fMRI block tasks design.
The letter H in the red box represents the house block, the letter F in the blue box represents the face block, and the white cross in the black box represents the rest block. The BNR task is shown on the top, while the BR task is shown on the bottom.
Figure 2.
Diagram illustrating signal processing steps.
In the green boxes the steps concerning the BNR ROI signals are described, in the blue boxes the steps concerning BR ROI signals are described, and in the orange boxes the steps in common for both signals are described.

Figure 3.
Example of resulting BOLD activity from GLM single-subject analysis of BNR-localizer task.
Picture A shows t-contrast activations of face-house (FWE<0.05) in BNR time-course of PPA on top and FFA ROI on the bottom. Picture B shows t-contrast activations of house-face (FWE<0.05) in BNR-localizer time-course of FFA on top and PPA ROI on the bottom.
Figure 4.
Bar plot of ANN percentage of successes for each subject.
The plot shows in ordinate the percentage of time points correctly allocate to conditions (house or face) and in abscissa the number associated to the participants.

Figure 5.
Examples of stimuli distributions after 1000 output repetitions.
In panel A on top the bar histogram shows for subject 7 the results of the 1000 reiterations using the BR task time course signal. In y axis is represented the percentage number (frequency) of house and face over all time points in a reiteration, and in the x axis the percentage number of reiterations (events) in which we obtained a determined frequency of houses and faces over all 1000 reiterations. In the plot on the bottom of panel A the BR time course signal has been replaced with Rest time course signal. In panel B the same bar histograms, for BR and rest time courses, are shown for the subject excluded because he did not experience the BR phenomenon.
