(A) The theta scalp distribution revealed two strong clusters of activity: one in the frontal site and one in the bilateral parieto-occipital sites. (B) We included the scalp theta distribution for both conditions above. We have focused our analysis on the electrodes with the largest differences. Indeed, the main difference between conditions is mainly a global increase of the theta signal in the direction condition as compared to distance condition, independently of sites. (C) Example of a typical raw channel focused on PO3-PO4 (maximum effect) during question distance (S1) and response distance (S101) for a correct answer (S128).
